H2o

1 mole H2 = 2.016g H2 = 6.022 x 1023 molecules H210g H2 x 1mol H2/2.016g H2 x 6.022 x 1023 molecules H2/1mol H2 = 3 x 1024 molecules H2 (rounded to 1 significant figure)

Given/Known:1mole of H2 = 2.01588g H21mole of H2 = 6.022 x 1023 molecules H21) Convert molecules of H2 to moles of H2 by doing the following calculation.9.4 x 1025 molecules H2 x (1mol H2/6.022 x 1023 molecules H2) = 156mol H22) Convert the moles of H2 to mass in grams of H2.156mol H2 x (2.01588g H2/1mol H2) = 314g H2

The chemical reaction is:N2 + 3 H2 = 2 NH3For six molecules of nitrogen N2 18 molecules of hydrogen H2 are needed.

Yes. The diatomic molecules of the elements include primarily H2, N2 & O2; Examples of molecular compounds include: H2O, C2H5OH, NH3, CO2, DNA and sugar.

The gram molecular mass of H2 is 2g.

Balanced equation. ( this is a equilibrium reaction ) H2 + CO2 >< H2O + CO this is one to one, so 65.1 moles is the answer. 65.1 mols H2O (1mol H2/1mol H2O ) = 65.1 moles H2

2 moles.
