Question

How many grams are in 5.00 mol of sodium chloride (NaCl)?Express your answer numerically in grams.

Answer 1

The mass of NaCl is 292.5 grams

Explanation:

Given information

The number of moles of NaCl is 5.00 mol

Let x represents the mass in grams of NaCl

To calculate the mass in grams of NaCl, we will need to apply the below formula

`\text{mole = }\frac{\text{ mass}}{\text{ molar mass}}`

The next step is to find the molar mass of NaCl since we are not given in the question provided

According to the periodic table, the molar mass of sodium is 23 g/mol and the molar mass of chlorine is 35.5 g/mol

molar mass of NaCl = 23 + 35.5

Molar mass of NaCl = 58.5 g/mol

To find the mass of NaCl, we will need to input the given data into the above formula

`\begin{gathered} \text{mole = }\frac{mass}{\text{molar mass}} \\ \text{Recall that, mass = x} \\ 5\text{ = }(x)/(58.5) \\ \text{cross multiply} \\ x\text{ = 5 }*\text{ 58.5} \\ x\text{ = 292.5 grams} \end{gathered}`

Therefore, the mass of NaCl is 292.5 grams
