Mass and the number of mole in a given sample are related quickly with the equation #MOLE = MASS/MOLAR MASS Where the mass is in grams. Now, we know that the number of mole is one, and the molar mass can be found with any Periodic Table - 1.00794 abouts. Now, the equation reads 1 = MASS/1.00794 This can be rearranged through simple mathematics into 1*1.00794 = MASS/1.00794 * 1.00794 Or 1*1.00794 = MASS Since anything multiplied by one is itself, this can be simplified to 1.00794 = MASS So, the mass of 1 mole of Hydrogen is 1.00794 grams. Also, your question was a sentence :p

An excess of Mg is reacted with 1 mole of HCl dissolved in water- determine the mass of hydrogen produced?
The reaction between magnesium and hydrochloric acid produces hydrogen gas according to the equation: Mg + 2HCl -> MgCl2 + H2. For every 1 mole of magnesium reacted, 1 mole of hydrogen gas is produced. Using the molar mass of hydrogen (1 g/mol), the mass of hydrogen produced would be 1 gram when 1 mole of magnesium is reacted.
What is the mole ratio of C5H12 to H2 in the following reaction?

When zinc reacts wiht sulfuirc acid what mass of hydrogen is produced from 31.8g of zinc?
To calculate the mass of hydrogen produced when 31.8g of zinc reacts with sulfuric acid, you need to first balance the chemical equation. The balanced equation is: Zn + H2SO4 → ZnSO4 + H2. Then, use the molar ratio from the balanced equation to convert the mass of zinc to moles, and then to moles of hydrogen. Finally, convert moles of hydrogen to mass using the molar mass of hydrogen.
How many grams of O2 are required to completely react with 2g of H2?
The balanced chemical equation for the reaction of H2 with O2 to form H2O is: 2H2 + O2 -> 2H2O From the equation, it can be seen that 1 mole of O2 reacts with 2 moles of H2. Since the molar mass of H2 is 2 g/mol and the mass given is 2g, there is 1 mole of H2. Therefore, 1 mole of O2 is needed, which is 32g.

How many grams of water form when 1.24L of H2 gas at STP reacts with O2?
When 1.24 L of H2 gas reacts with O2 at STP, the mole ratio between H2 and H2O is 2:2. This means that for every 1 mole of H2 gas reacting, 1 mole of water is formed. Using the ideal gas law, you can calculate the number of moles of H2 gas reacting, and then use the mole ratio to determine the number of moles of water formed. Finally, you can convert moles of water to grams using the molar mass of water.
