Chemistry

There are 1.78 moles in 40.0 L of He gas at STP

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 1 atm (STP)

V = Volume of gas = 40.0 L

n = number of moles = ?

R = gas constant = 0.0821Latm/Kmol

T =temperature = 273K (STP)

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

$n=\frac{1atm\times 40.0L}{0.0821Latm/K mol\times 273K}=1.78moles$

Thus there are 1.78 moles in 40.0 L of He gas at STP
