at stp, how many moles of h2 gas are contained within a 112 l container?
Answer
Explanation:
Step1: Recall molar - volume at STP
At STP (Standard Temperature and Pressure, 0°C and 1 atm), the molar volume of any ideal gas is $V_m = 22.4\ L/mol$.
Step2: Use the formula for number of moles
The formula to calculate the number of moles $n$ of a gas is $n=\frac{V}{V_m}$, where $V$ is the volume of the gas and $V_m$ is the molar - volume. Given $V = 112\ L$ and $V_m=22.4\ L/mol$. $n=\frac{112\ L}{22.4\ L/mol}$
Step3: Calculate the number of moles
$n = 5\ mol$
Answer:
5 mol
