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

The moles of gas is 0.009474 moles.

Step-by-step 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=(PV)/(RT)`

Where, P = pressure

V = volume

R = gas constant

T = temperature

Put the value into the formula

`n=((346)/(760)*0.526)/(0.08206*(35+273))`

`n=0.009474\ moles`

Hence, The moles of gas is 0.009474 moles.
