Question

b) calculate the number of moles in 3.011×10

Answer 1

Answer: 0.5 moles

Explanation:-

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

Given :

Number of atoms of carbon = $3.011\times 10^{23}$

Thus $6.023\times 10^{23}$ atoms of carbon = 1 mole

$3.011\times 10^{23}$ atoms of carbon=$\frac{1}{6.023\times 10^{23}}\times 3.011\times 10^{23}=0.5 moles$
