Question

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

Answer 1

Answer:

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

$n=\dfrac{PV}{RT}$

Where, P = pressure

V = volume

R = gas constant

T = temperature

Put the value into the formula

$n=\dfrac{\dfrac{346}{760}\times0.526}{0.08206\times(35+273)}$

$n=0.009474\ moles$

Hence, The moles of gas is 0.009474 moles.
