Question

How many atoms of hydrogen are in 0.238mol of C2H5OH?

Answer 1

Explanation:

Molar mass of c2h5oh = 46g/mol

Number of moles of c2h5oh =n=0.238 mole

Now,

∴ 1 mol c2h5oh contains 6 gram atoms of hydrogen(H)

∴ 0.238 mol c2h5oh contains==6×0.238=1.428 gram atom of H.

Now,

1gm atom of H contains =6.022×10^23

atoms of H.

1.428gram atom of hydrogen contains = 6.022×10^23

×1.428=8.599×10^23
