Question

A container holds 4g of hydrogen gas. How many moles of the gas does it contain?

Answer 1

The container holds 2 moles of hydrogen gas.

Step-by-step explanation:

To find the number of moles of hydrogen gas in a container, we need to use its molar mass. The molar mass of hydrogen gas (H₂) is approximately 2 g/mol. Since the container holds 4g of hydrogen gas, we can calculate the number of moles using the formula:

Number of moles = Mass of substance / Molar mass

Number of moles = 4g / 2 g/mol = 2 mol

Therefore, the container contains 2 moles of hydrogen gas.

Answer 2

3.96849018791 moles of hydrogen

Step-by-step explanation:

1 mole of hydrogen = 1.00794 g of hydrogen

1/x = 1.00794/4

(1*4)/1.00794 = 3.96849018791
