Question

Calculate the number of moles in 50g CaCO3 ​

Answer 1

Explanation:

$number \: of \: moles = \frac{given \: weight}{molecuar \: weight} \\ \\ moles = \frac{50}{100} \\ \\ moles = 0.5$

therefore, number of moles in 50 gram CaCO3 is 0.5

Answer 2

$\huge\underline\orange{\mathcal Answer}$

$\large\blue{\boxed{\mathcal Mole\:Of\:CaCO3=0.5 mole}}$

$\huge\underline\orange{\mathcal Solution}$

$\large{\boxed{\mathcal Mole={\frac{Mass}{Molar\:Mass}}}}$

Given :-

Mass of CaCO3 = 50g

Molecular Mass of CaCO3 = 40+12+16+16+16=> 100g

$\large{\mathcal Mole={\frac{50}{100}}}$

$\large{\mathcal Mole\:Of\:CaCO3\:is\:0.5\:moles}$
