Answer 1

INFORMATION:

We have the next compound:

- calcium nitrate

And we must find its molar mass using the periodic table

STEP BY STEP EXPLANATION:

First, we must identify the chemical formula for the compound:

- calcium nitrate: Ca(NO3)2

Second, we must identify the molecular weight of each element using the periodic table

- Ca: 40.08 g/mol

- N: 14.01 g/mol

- O: 16.00 g/mol

Third, We must replace the molecular weights in the chemical formula multiplying by the subscript

`40.08+(14.01+(16.00*3))*2`

Finally, we must simplify and the result will be the molar mass of calcium nitrate

`\begin{gathered} =40.08+(62.01)*2 \\ =40.08+124.02 \\ =164.10 \end{gathered}`

So, the molar mass would be 164.01 g/mol

ANSWER:

164.10 g/mol
