Question

Calculate the particle quantity of 5.060 grams of CuSO4

Answer 1

The number of moles of a molecule is calculated using the following formula;

$Mole=\dfrac{mass}{molar \ mass}$

Molar mass $CuSO_4=159.609g/mol\newline$

Mass$=5.060g$

Substituting the values into the formula;

$Mole=\dfrac{5.060}{159.609}$

$=0.0317$

The particle quantity of $CuSO_4=0.0317mol$
