Explanation:
See the image uploaded for the percent error formula
Work:
Theoretical Value - Accepted Value/Accepted Value * 100
= (24.7-24.3)/24.3 * 100
= 0.4/24.3 * 100
= 0.0164609053 * 100
= 1.64609053
Can be rounded to 1.65%
First, we must calculate the moles of lithium ions required using:
Concentration = moles / liter
500 ml = 0.5 L
0.125 = moles / 0.5
moles = 0.0625
Lithium phosphate has the formula Li₃PO₄, meaning each mole of lithium phosphate releases three moles of lithium ions. The moles of lithium phosphate required will be:
0.0625 / 3 = 0.021 mol
The mass of one mole of lithium phosphate is 116 g/mol
Mass of lithium phosphate required = 0.021 x 116
Mass of lithium phosphate required = 2.42 grams
