Jawaban:
the mass of the other chair is 15 Kg
Penjelasan dengan langkah-langkah:
Diketahui : average (rata-rata) mass of 2 chair 12 Kg
The mass of one of the chairs is 9 Kg
the mass of the other chair = x
[tex] \frac{9 + x}{2} = 12 \\ x = 15[/tex]
4. The average mass of 9 sheep is 35 kg. The average mass of 9 sheep and 1cow is 64 kg. What is the mass of the cow?
Jawaban:
The mass of the cow is 325kg
Penjelasan:
TobeKnown:
9 sheep = 35 kg
9 sheep + 1 cow = 64 kg
TobeAsked:
mass of the cow = . . . . ?
Solving:
as 9 sheep + 1 cow is 64 kg, so that the total average mass of those 10 animals = 64 kg
total average = [tex]\frac {(9 × 35) + (cow)}{10}[/tex] = 64
(315) + (cow) = 64 × 10
315 + cow = 640
cow = 640 - 315
cow = 325 kg
5. The mass of a bag of 10 identical cubes is 768 g. The mass of the bag is 120 g. What is the mass of each cube?
Answer:
64.8 g
Explanation with steps:
mass of 10 cubes = total mass - mass of the bag
mass of 10 cubes = 768 g - 120 g
mass of 10 cubes = 648 g
therefore, the mass of each cube is 648 g / 10 = 64.8 g
6. 2. Magnesium has relative atomic mass of 24.31 amu. There are three naturally occurring isotopes of magnesium which are Mg-24, Mg-25 and Mg-26. The relative abundances of isotope Mg-24 (23.985 amu) is 79.0%. If the relative isotopic mass of Mg-26 is 25.983 amu and the ratio of fractional abundance of Mg-25 to Mg-26 is 0.908, find the relative isotopic mass of Mg-25. (5 marks) [25.04 amu]
Jawaban:
Hasil berupa 24,31 amu diperoleh dari proporsi massa relatif isotop antara Mg-24, Mg-25, dan Mg-26. Massa relatif isotop Mg-25 sebesar 25,488 amu.
The relative isotopic mass of Mg-25 is 25.488 amu.
Penjelasan:
Persentase Mg-25 dan Mg-26
[tex]Mg - 25,Mg - 26 = 100\% - 79\%[/tex]
Jumlah Mg-25 dan Mg-26 adalah 21%
[tex]Mg - 25 =[/tex][tex]\[\frac{{0,908}}{{(1 + 9,08)}} \times 21\% \][/tex]
[tex]Mg - 25 = 9,994\%[/tex]
Perhitungan massa relatif isotop
[tex]24,31 = (79\% \times 23,985) +[/tex][tex](19,068\% \times X) +[/tex][tex](11,006\% \times 25,983)[/tex]
[tex]X = 25,04[/tex]
Sehingga massa relatif isotop Mg-25 adalah 25,04 amu.

7. a kitten and a basket has a mass of 3 kg . A hamster and a similar basket has a mass of 1.4kg . the mass of the kitten is 5 times the mass of the hamster .a. what is the mass of the hamster ? , b. what is the mass of the kitten ?
kitten = x ,hamster = y and baskest = z
x+z = 3 kg
y+z = 1,4 kg
z = x- y = 3 kg - 1,4 kg = 1,6 kg
x+y = 4,4 kg - 1,6 kg = 2, 8 kg
x = 5y
5y +y = 2,8 kg
6y = 2,8 kg
y = 2,8 kg /6
y = 0,47 kg
x = 5y
= 5 * 0,47 kg
= 2,35 kg
a. mass off hamster = 0,47 kg
b. mas off kitten = 2,35 kg
bonus...mass of basket = 1,6 kg

Diketahui:
Berat semangka = 7/1 kg
Berat apel = 2/5 kg kurang dari semangka
Maka:
a. Berat apel = 7/1 - 2/5
= 35/5 - 2/5
= 33/5 = 6 3/5
b. Berat apel dan semangka = 7/1 + 6 3/5
= 35/5 + 33/5
= 68/5 = 13 3/5

13. The mass of a dictionary is 1.28 kg. The mass of the dictionary is twice the mass of a storybook. The mass of an encyclopaedia is 1.4 kg more than storybook. What is the mass of the encyclopaedia?
Jawaban:
2.04 kg
Penjelasan dengan langkah-langkah:
Jika berat sebuah kamus 2 kali berat buku cerita, maka berat buku cerita adalah setengah dari berat kamus. Sehingga berat ensiklopedia adalah
1.4 kg + (1.28 ÷ 2) kg
= 1.4 kg + 0.64kg
= 2.04 kg
