Answer 1

Answer:

here you go

Explanation:

C

v

for a monoatomic gas at constant volume is

2

3R

≈3 cal−mol

−1

K

−1

Let the atomic weight of the gas be w

∴w grams of the gas requires the 3 cal of heat to raise its temperature by 1K.

∴ 1 gram of gas will require

w

3

cal of heat to raise its temperature by 1K.

∴ 1 kg of gas will require

w

3

kcal of heat to raise its temperature by 1K.

In the question, the above quantity is given to be 0.075 kcal kg

−1

K

−1

∴

w

3

=0.075

Solving this, we get w=40
