How much mass would a mole of hydrogen molecules contrin? Recall that hydrogen is diatomic. 4 g/mol

To calculate the mass of a mole of hydrogen molecules, we need to consider that hydrogen is diatomic, meaning each molecule consists of two hydrogen atoms.<br /><br />1. The atomic mass of a single hydrogen atom is approximately 1 gram per mole (g/mol).<br /><br />2. Since hydrogen is diatomic (\(H_2\)), a molecule of hydrogen has a mass of:<br /> \[<br /> 2 \times 1 \, \text{g/mol} = 2 \, \text{g/mol}<br /> \]<br /><br />Therefore, one mole of hydrogen molecules (\(H_2\)) would have a mass of 2 grams, not 4 grams.
