Question

find the mass and no. of molecules in calcium carbonate when the no. of moles present in calcium carbonate is 6, you can write direct answer also.. tell fast it's urgent​

Answer 1

Answer:

CaCO

3

atomic mass = 40+12+3×16

=100

moles =

atomicmass

gramweight

=

100

20

(given)

=0.2 moles

Answer 2

Answer:

Molecular weight of CaCO^3

=40+12+(16×3)=100 g

Given weight =20 g

Therefore no. of moles =

Molecular weight/Given weight

= 100/20 =0.2 moles.
