The number of moles in 2.93 g of Li2O in corrext sig figs
2 answers:
Answer:
Mass of Li2O = 2.93g
Molecular mass of Li2O = 29.88g/mol
No of mole of Li2O = Mass/Molar mass
No of mole of Li2O = 2.93/29.88
No of mole of Li2O = 0.0981mol
Answer:
0.1 mol
Explanation:
Number of mole= mass/molar mass
lithium have a mass number of 7 and oxygen have a mass number of 16.
so, (7x2) + 16
= 30
therefore, number of moles = 2.93/30
= 0.10
