How many hydrogen atoms are present in 32 grams of methane?
Answered by Bill
Methane =CH4
Molecular mass of CH4 is 16
There are 32g of CH4

Find the moles of CH4 by dividing it's mass by its molecular mass:
n=32/16
n=2 moles (CH4)

Since methane (CH4) contains 4 hydrogen atoms per mole, then 2 moles of methane would mean there are 8 moles of hydrogen (2 x 4 = 8)

Then multiply the amount of moles of hydrogen by Avogadro's number:
8x6.022x10^26=4.8176e+27 hydrogen atoms
