Answer: The volume of gas is 48.69L.

Step-by-step explanation:

To calculate the number of moles of gas, we use the equation:


\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Given mass of water = 36 g

Molar mass of water = 18 g/mol

Putting values in above equation, we get:


\text{Moles of water}=(36g)/(18g/mol)=2mol

Now, to calculate the volume of gas, we use the equation given by ideal gas, which is:


PV=nRT

where,

P = pressure of the gas = 100 kPa

V = volume of the gas = ? L

n = Number of moles of gas = 2 mol

R = Gas constant =
8.31\text{ L kPa }mol^(-1)K^(-1)

T = temperature of the gas = 293 K

Putting values in above equation, we get:


100kPa* V=2mol* 8.31\text{ L kPa }* 293K\\\\V=48.69L

Hence, the volume of gas is 48.69L.
