# Determine the pressure in a 125 − L tank containing 56 . 2 kg of oxygen gas at 21  ° C .

Interpretation Introduction

Interpretation:

The pressure of oxygen gas should be calculated.

Concept Introduction:

According to ideal gas equation:

PV=nRT

Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature.

The value of Universal gas constant can be taken as 0.082 L atm K1 mol1.

Mass of gas can be calculated from number of moles and molar mass as follows:

m=n×M

Here, n is number of moles, m is mass and M is molar mass.

Explanation

Given Information:

The volume of tank is 125 L, mass of oxygen gas is 56.2 kg and temperature is 21 C.

To calculate the pressure, first calculate the number of moles of gas using the equation as follows:

n=mM

Molar mass of oxygen is 32 g/mol thus, number of moles will be:

n=56.2 kg(103 g1 kg)32 g/mol=1756.25 mol

Now, calculate pressure of gas as follows:

P=nRTV

Convert the temperature from C to K as follows:

0 C=273
