What is the mass of 1 mole of lithium?

Korolek [52]

<u>Answer:</u> The mass of 1 mole of lithium is 6.941 grams.

<u>Explanation:</u>

To calculate the mass of a compound or element, we use the formula used to calculate the number of moles:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Where,

Number of moles of lithium = 1 mole

Given mass of lithium = ? g

Molar mass of lithium = 6.941 g/mol

Putting value in above equation, we get:

$1mole=\frac{\text{Given mass}}{6.941g/mol}\\\\\text{Mass of lithium}=6.941g$

Hence, the mass of 1 mole of lithium is 6.941 grams.
