An agricultural chemist is preparing a liquid fertilizer containing hydrated calcium nitrate, $Ca(NO3)2⋅4H2O\text{Ca(NO}_3)_2 \cdot 4\text{H}_2\text{O}$ . To calculate the correct nutrient dosage, they must determine the relative formula mass ( $M_r$ ) of this compound.

Relative atomic masses ( $A_r$ ):

$Ca=40.1\text{Ca} = 40.1$
$N=14.0\text{N} = 14.0$
$O=16.0\text{O} = 16.0$
$H=1.0\text{H} = 1.0$
