Answer 2

Answer:

The weight of 1 mole of gaseous sample is 40 g

Explanation:

1 Liter (NTP) = 1.78 g of density  

1 mole of gaseous sample (NTP) contains = volume of 22.4 liters.

To find, 22.04 liters = ? of density of gas  

1.78 g of gas = 1 L at NTP $\rightarrow$ equation 1

x g of gas = 22.4 liters $\rightarrow$ equation 2  

Cross multiply the equation (1) and (2)

$\frac{1.78}{x}=\frac{1}{22.4}$

x $\times$ 1  = 1.78 $\times$ 22.4

x = 39.9

x = 40 g
