Question

Calculate the no. Of atoms in 100gm of water

Answer 1

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.

Answer 2

Answer:

Explanation: avagadros number=6.02×10^23 and molecular mass of water is 18. Estimate the number of electrons in 100 g water.
