Respuesta :
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.
