<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:

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:

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