Answer:

33.45 * 10^23

Explanation:

H20 has the amu/u of 2*1+16 = 18

which means there are 6.023 * 10^23 molecules in 18 gms of H20

so in 100 grams use proportion

N_{A} = Avogadros number

N_{A} : 18 :: x : 100

=> x = N_{A} * 5.555

=> x = 33.45 * 10^23

Hope this helps you

Plz mark as brainly.
