Question

Can you help me how do I get the grams?

Answer 1

Answer:

$1290g\text{ NaBr}$

Explanation:

Here, we want to get the number of grams in 12.5 moles NaBr

To get this, we have to multiply the number of moles by the molar mass of NaBr

The molar mass of NaBr is 103 g/mol

Thus, we have the mass as:

$\begin{gathered} Mass\text{ = number of moles }\times\text{ molar mass} \\ =\text{ 12.5 }\times\text{ 103 = 1,287.5 g} \end{gathered}$

This can be approximated to 1290 which is the nearest whole number
