DETERMINE THE NUMBER OF MOLES OF H IN EACH SAMPLE? PLEASE! NEED BIG HELP?!?
I need assistance in determining the number of moles of hydrogen (H) in each of the following compounds:
a. 4.67 mol H₂O
b. 8.39 mol NH₃
c. 0.117 mol N₂H₄
d. 35.8 mol C₁₀H₂₂
Could someone please help me with this? Thank you!

so in a) you have H2O, so you have 2 moles hyrdogens per 1 mole of H2O, so you have 2 x 4.67 = 9.34 moles of hydrogen
b) 3 x 8.39 = 25.17 moles of H
c) 0.117 x 4 = 0.468
d) 35.8 x 22 = 787.6
seems difficult but it’s actually really easy!

use the equation moles = mass/molar mass Molar mass you get off your periodic table and your mass is given. Molar mass is the sum of the molar lots of the climate interior the question i.e molar mass of NaCL = molar mass of Na + Molar mass of Cl. you need to have the means to do the calculations now.
