Solve the following pls. Calculate the number of grams in these quantities:
1. 0.0600 mol HC2H302
2. 4.50 x10^21 molecules glucose C6H2O6
2 answers
1. Each mole of HC2H302
has a mass of 60.0 g
Multiply that by 0.06 mole for the answer.
2. That number of molecules is
4.5*10^21/6.02*10^23 = 7.48*10^-3 moles
(You get that by dividing by Avogadro's number)
Each mole has a mass of 110 g. (You get that from the compound formula)
That would be 0.823 g
has a mass of 60.0 g
Multiply that by 0.06 mole for the answer.
