How many moles of H atoms are there in 1.37 moles of H20?

Question

Can someone explain to me how to do this? Thanks!!!!

Answer 1

2.74

1 mole of H20 has 2 moles of H

Use ratios.
1.37 moles H20 x (2 moles of H)/(1 mole of H20) = 1.37 moles of H

Answer 2

well there are 2 moles of H for every 1 mole of H2O because the chemical equation for water says that there are 2 H atoms and 1 O atom.

so to calculate the moles of H in 1.37 moles of H2O, you multiply.

1.37 moles H2O x 2 moles H / 1 mole H20 = 2.74 moles H

2 moles H / 1 mole H20 means that there are 2 moles of H for every 1 mole H2O

Answer 3

Since water is H2O, then each 1 mole of water( 2X1 + 16=18) has 2 moles of hydrogen atom.
Now, 1.37 mole has (1.37X2)/18
=.15 mole

Answer 4

Since each water molecule has 2 hydrogens in it (not one as in the previous post) you would have 1.37 x 2 moles of hydrogen in 1.37 moles of water! (2.74 moles of hydrogen/1.37 moles of H2O
