Question

Moles to grams 3 moles of LiBr

Answer 1

260.535 grams

Step-by-step explanation

Given:

Number of moles of LiBr = 3 moles

What to find:

The grams of LiBr in 3.0 moles of LiBr

Step-by-step solution:

The molar mass of LiBr from the periodic table = 86.845 g/mol.

You can now use the mole formula to determine the grams of LiBr in 3.0 moles LiBr.

`\begin{gathered} Mole=\frac{Mass}{Molar\text{ }mass} \\ \\ \Rightarrow Mass=Mole* Molar\text{ }mass \\ \\ Mass=3.0\text{ }mol*86.845\text{ }g\text{/}mol \\ \\ Mass=260.535\text{ }grams \end{gathered}`

3 moles of LiBr to grams is 260.535 grams LiBr
