Solution
To calculate the number of moles in a gas at STP (Standard Temperature and Pressure), we can use Avogadro's law which states that one mole of any gas at STP occupies a volume of 22.4 L.
Step 1: Identify the given volume of the gas. In this case, it is 54.0 L of nitrogen dioxide.
Step 2: Use the formula for Avogadro's law, which is:
Number of moles = Volume of gas / Volume of one mole at STP
Step 3: Substitute the given values into the formula:
Number of moles = 54.0 L / 22.4 L/mol
Step 4: Calculate the result:
Number of moles = 2.41 mol
So, the number of moles in 54.0L of nitrogen dioxide at STP is 2.41 mol.
