6.17749 would be the mass

The mass of lithium metal that is used in lithium batteries is 6.17 grams,  this can be calculated by using number of moles formula.

Number of moles:

It is defined as the ratio between mass and molar mass.

It is given by:

Number of moles = mass / Molar mass

What information do we have?

Number of moles= 0.89 moles

Molar mass of Lithium metal= 6.941 g/mol

To find:

Mass of Lithium metal=?

On substituting the values

n= m/M

0.89 = m/ 6.941

m= 0.89*6.941

m= 6.177 grams

Thus, the mass of lithium metal is 6.177 grams.
