Question

26.0 g Ca

5.10 g S

41.0 g H2O

160.0 g O2

How many grams of the compound are in 5.50 moles of propane?

How many moles of the compound are in 55.0 g of propane?

How many grams of carbon are in 55.0 g of propane?

Mg(s)+AgNO3(aq)Mg(NO3)2(aq)+Ag(s) express your answer as a chemical equation.

Al(s)+CuSO4(aq)Cu(s)+Al2(SO4)3(aq) express your answer as a chemical equation.

Pb(NO3)2(aq)+NaCl(aq)PbCl2(s)+NaNO3(aq) express your answer as a chemical equation.

Al(s)+HCl(aq)AlCl3(aq)+H2(g) express your answer as a chemical equation.

1) How many grams of the compound are in 5.50 moles of propane ?

mass of 5.50 moles of propane = moles x molar mass = 5.5 mol x 44 g/mol = 242 g

2) How many moles of the compound are in 55.0 g of propane?

Moles of propane = mass / molar mass

= 55 g/ 44 g/mol

= 1.25 mol

3) The balanced chemical equations are

Mg(s)+ 2 AgNO3(aq) Mg(NO3)2(aq)+ 2Ag(s)

2Al(s)+ 3CuSO4(aq) 3Cu(s) + Al2(SO4)3(aq)

Pb(NO3)2(aq) + 2NaCl (aq) PbCl2(s)+ 2 NaNO3(aq)

2Al(s)+ 6HCl(aq) 2AlCl3(aq) + 3H2(g)
