Question

The total number of neutron present in 54 mL OR H2O(L) are:
(1) 3 (2) 30
(2) 24 (4) None of these ​

Answer 1

Answer:

Gram molecular mass of h2O = 18 g in one mole

so, 54÷18=3mole of h2O molecules

since, no. of nuetron in O= 8

no. of nuetron in h=0

so, total no. of nuetron in a h2O molecule = 8

8 in 1 mole

so, in three mole= 8×3=24 ans
