Question

(4.69 X 10^22)/(6.02 X 10^23) = 0.08 moles

Answer 1

\[\frac{4.69\times10^{22}[\text{molecules}]}{6.02\times10^{23}[\text{molecules}/\text {mole}]}=\frac{4.69}{6.02}\times10^{22-23}[\text{mole}]\\\qquad\qquad\qquad\qquad\qquad\qquad
=0.779\times10^{-1}[\text{mole}]\\\qquad\qquad\qquad\qquad\qquad\qquad
=0.0779[\text{mole}]\\\qquad\qquad\qquad\qquad\qquad\qquad
\approx0.08[\text{mole}]\]
