A sample of gas has a volume of 526 mL at 346 mmHg and 35.0°C. Determine the moles of gas.

The moles of gas is 0.009474 moles.

Explanation:

Given that,

Volume = 526 mL

Pressure = 346 mmHg

Temperature = 35.0°C

We need to calculate the moles of gas

Using formula of ideal gas

Where, P = pressure

V = volume

R = gas constant

T = temperature

Put the value into the formula

Hence, The moles of gas is 0.009474 moles.
