Na (sodium) has a molar mass of 23g.
Cl (chlorine) has a molar mass of 35g.
To find the molar mass of NaCl, add the individual elements' masses together:
![23 + 35 = 58](https://img.qammunity.org/2019/formulas/chemistry/middle-school/yn1fjuyipuacx8bkuop6fasnm1z1m54td4.png)
The molar mass of NaCl is 58g.
To find the mass of 3.45 moles of NaCl, multiply the moles by its mass:
![58 * 3.45 = 200.1](https://img.qammunity.org/2019/formulas/chemistry/middle-school/odhloeauo4lee5lzb79bo4cvahup0qo8sa.png)
There are
200.1 grams in 3.45 moles of NaCl.
