Question

how many grams of O is present in 50 gram of caco3

Answer 1

Explanation:

heya.

the molecular weight of CaCO3

is hundred grams.

=]

in this the molecular weight of oxygen is 16 × 3 = 48

=] for hundred grams of CaCO3 48 grams of oxygen is present

then then for 50 grams of CaCO3 how many grams of oxygen is present

= 48/2 = 24grams
