If 5 litres of a liquid has a mass of 850 g what is the density of the liquid in g/cm³
1. If 5 litres of a liquid has a mass of 850 g what is the density of the liquid in g/cm³
Jawaban:
0,17 g/cm^3
Penjelasan:
mass = 850 g
volume = 5 litres = 5.000 cm^3
density = mass/volume
= 850/5.000
= 0,17 g/cm^3
2. liquid x has a mass of 9.8 grams and volume of 1.4 centimeter cubed what si the density of liquid x
Jawaban:
0.0001428571428
Penjelasan:
Density
9.8 g = 9.8 / 1000 = 0.0098 Kg
1.4 cm^3 = 1.4 / 1000000 = 0.0000014 m^3
ρ = m/V
= 0.0000014/0.009.8
= 0.0001428571428

Dari pernyataan berikut, manakah yang tidak memengaruhi tekanan hidrostatis dalam wadah tertutup ?
A. Luas permukaan cairan
B. Kekuatan medan gravitasi
C. Massa jenis zat cair
D. Kedalaman zat cair
Jawaban :A. Area of liquid surface
Pendahuluan :Hi ! Kali ini kita akan membahas mengenai tekananhidrostatis. Tekanan hidrostatis masih dalam dimensi yang sama dengan dimensi tekanan pada zat padat. Hanya saja, tekanan hidrostatis ini dimiliki oleh zat cair. Tekanan hidrostatis yaitu tekanan yang diakibatkan oleh komponen dari zat cair itu sendiri. Tekanan hidrostatis ini disimbolkan dengan "[tex] P_h [/tex]" dan memiliki satuan N/m² atau Pa.
Pembahasan :Tekanan hidrostatis dipengaruhi oleh massa jenis zat cair ([tex] \rho [/tex]), percepatan gravitasi (g), dan kedalaman zat cair itu sendiri (h). Pengaruh antar unsurnya terhadap nilai tekanan hidrostatis yaitu :
Massa jenis zat cair([tex] \bold{\rho [/tex]}), yaitu tingkat kerapatan zat cair. Semakin tinggi nilai massa jenis zat cair, zat cair akan semakin rapat. Di dasar suatu wadah, maka tekanan yang dirasakan akan semakin besar.Percepatangravitasi(g), yaitu tingkat interaksi setiap benda ke pusat interaksi massa. Percepatan gravitasi jika Anda di Bumi akan selalu sama antara dengan rerata paling stabil 9,81 m/s² atau sering dibulatkan menjadi 10 m/s². Semakin tinggi nilai percepatan gravitasi, maka tekanan hidrostatis akan semakin besar.Kedalaman(h), yaitu kedalaman cairan yang diukur dari bagian atas permukaan zat cair hingga ke dasar bagian wadah. Tekanan hidrostatis tertinggi jelas dirasakan pada bagian dasar wadah karena itu adalah titik terdalamnya. Semakin dalam suatu wadah, maka tekanan pada dasar wadah semakin besar pula.Dari pilihan pada soal, hanya luaspermukaancairan lah yang tidak termasuk unsur penyusun tekanan hidrostatis.

2.mass = the density × volume
= 2,7 g / ml × 20 ml
= 54 gram
3.the density= mass / volume
= 10 / 20
= 0,5 g / ml

6. A measuring cylinder has a mass of 120 g when empty. When it contains 50 cm3 of a liquid, the total mass of the measuring cylinder and the liquid is 160 g. What is the density of the liquid?
Mass of cylinder (empty) = 120 gram
Mass of cylinder (with liquid) = 160 gram
Volume of liquid = 50 cm³
Density of the liquid (ρ) = ?
Answer:
Find the mass of liquid
With liquid - Empty
= 160 gram - 120 gram
= 40 gram
So, the mass of the liquid is 40 gram
Find the density of the liquid
[tex]\rho=\frac{mass}{Volume} \\\rho=\frac{40\ gr}{50\ cm^3} \\\rho=\frac{40}{50}\ gr/cm^3 \\\rho=\frac{4}{5}\ gr/cm^3 \\\boxed{\rho = 0,8\ gr/cm^3}\\or\\\boxed{\rho = 800\ gr/cm^3}\\[/tex]

8. Mercury is a liquid metal. Its density is 13.6 g/cm' Mercury is supplied in a plastic bottle whose volume is 50 cm. The empty bottle has a mass of 25.09. Calculate the mass of the bottle when it is filled with mercury.
Jawaban:
densitas = massa dibagi volume. Jadi, massa = densitas x volume
Massa merkuri: 13.6 x 50 = 680 g/cm2
Massa botol: 25.09
Total massa botol penuh merkuri: 680 + 25.09 = 705.09
Penjelasan:
Kalau ngikutin rumus fisika sih itu ya rumusnya. m = P x V
Cuma di soal itu setiap satuannya gak dicantumin detail. Jadi total massanya kalau tak hitung 705.09 g/cm2. Tapi ya aneh juga volume kok satuannya cm bukan cm3.
Semoga tidak keliru ya
9. Calculate the KE of the liquid flowing in a pipe 5 cm inner diameter at the rate of 500 kg/min. The density of the liquid is 1.15 g/cm³.
Jawaban:
The kinetic energy (KE) of the liquid flowing in the pipe can be calculated as follows:
First, we need to determine the velocity of the liquid. This can be calculated using the equation:
v = Q / A
where v is the velocity (m/s), Q is the flow rate (m^3/s) and A is the cross-sectional area of the pipe (m^2).
To convert the flow rate from kg/min to m^3/s, we need to multiply the flow rate by the conversion factor of 1/60. Then, we need to convert the density from g/cm³ to kg/m³:
Q = (500 kg/min) * (1/60 s/min) * (1000 g/kg) = 50/6 m^3/s
ρ = 1.15 g/cm³ * (1000 cm³/m³) = 1150 kg/m³
Now, we can find the cross-sectional area of the pipe:
A = (π/4) * d^2
d = 5 cm
A = (π/4) * (5 cm)^2 = 19.63 cm^2
A = (19.63 cm^2) * (0.01 m/cm^2) = 0.1963 m^2
Using the velocity and the cross-sectional area, we can now find the volume flow rate of the liquid:
v = Q / A = 50/6 m^3/s / 0.1963 m^2 = 156.41 m/s
Finally, we can find the kinetic energy of the liquid:
KE = 0.5 * ρ * v^2 * A
KE = 0.5 * (1150 kg/m³) * (156.41 m/s)^2 * (0.1963 m^2) = 174444.44 J/s = 174.44 kJ/s
