Question

What is the number of gram atoms present in 10 grams of caco3?

Answer 1

$\text{gram atom means number of mole.}$
$\text{we know,}\\\text{mole}=\frac{\text{given weight}}{\text{molecular weight}}$
here, given weight = 10g
molecular weight of CaCO3 = 100g/mol

mole = 10g/100g/mol = 0.1 mole

hence, 0.1 g atom

Answer 2

Answer:

0.1g

Step-by-step explanation:weight 10g , caco3=40+12+3×16=40+12+48=100g atwt/gmwt=10/100=0.1g
