To calculate the number of moles of helium in a given mass (g), you can use the formula:
[ \text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} ]
The molar mass of helium is approximately 4.00 g/mol. So, if you have a specific mass of helium, divide that value by 4.00 g/mol to find the number of moles.
