Question

Calculate the no. Of moles in 12.044×10^23 no.Of he atoms

Answer 1

Given;

• N(atoms) = 12.044 × 10²³
• n = moles = ?

${ N_{A} } =Avogadro's \: number \: \\ { N_{A} } \: = 6.022 \times {10}^{23}$

Thus using the formula;

$n \: = \frac{N}{ N_{A}}$

$n \: = \frac{12.044 \times {10}^{23} }{6.022 \times {10}^{23} } \\ n \: = \frac{12044}{6022} \\ n \: = 2 \: moles$
