Solution: Calculate the mass percent composition of lithium ion in Li 3PO4.a. 30.72 %b. 55.27 %c. 20.82 %d. 26.75 %e. 17.98 %


Calculate the mass percent composition of lithium ion in Li 3PO4.

a. 30.72 %

b. 55.27 %

c. 20.82 %

d. 26.75 %

e. 17.98 %


We are asked to calculate for the percent by mass (mass %) of  lithium ion (Li) in Li 3PO and to do that we’re going to use the mass percent formula shown below:

mass percent = mass element total mass of compound×100

For the percent by mass C, we’re going to rewrite the equation as:
