How many atoms of hydrogen do you have in 0.86 moles of ch4?

Answer 1

0.86 moles CH4 (4 mole H/1 mole CH4)(6.022 X 10^23/1 mole H)

= 2.1 X 10^24 atoms of hydrogen

Answer 2

In 0.86 moles of CH4, you have 5.16 x 10^23 atoms of hydrogen. This is because there are four hydrogen atoms in one molecule of CH4, making a total of 0.86 x 4 = 3.44 moles of hydrogen atoms, which can be converted to atoms using Avogadro's number.
