The formula mass of $C a {(N O_{3})}_{2}$ $Ca(NO_3)_2$ is $164.09 \cdot g \cdot m o l^{- 1}$ $164.09*g*mol^-1$ .

Explanation:

So how did we get that mass?

Well, in each formula units of $calcium nitrate$ $"calcium nitrate"$ there is one atom of calcium, 2 atoms of nitrogen, and 6 atoms of oxygen. If I take the atomic masses (from where?) and sum them appropriately:

$Formula mass of calcium nitrate$ $"Formula mass of calcium nitrate"$

$= (40.1 + 2 \times 14.01 + 6 \times 15.999) \cdot g \cdot m o l^{- 1}$ $=(40.1+2xx14.01+6xx15.999)*g*mol^-1$

$= ? ? \cdot g \cdot m o l^{- 1}$ $=??*g*mol^-1$ . Sum them up and waddya get?

Do you have to remember these numbers?
