If a typical aluminum beverage can weighs 13.5g, how much alum could you produce for every 210 cans collected? Show your work based on your own experiment.

My experiment is Aluminum recycling and here are my results: mass of aluminum can fragments = 0.4559g ; mass of alum produced = 6.2400g ; theoretical yield of alum, 2KA1(SO4)2•12H2O(s) = 8.01498g

20.5 km is equal to m

Na2CO3(aq) + CaCl2(aq) -------- 2NaCl(aq) + CaCO3 (s)

Calculate the volume (in mL) of 0.200 M CaCl2 needed to produce 2.00g of CaCO (s). There is an excess of Na2CO3

Molar mass of calcium carbonate= 100.09 g/mol

volume of calcium chloride =

what is the volume of calcium chloride?

Na2CO3(aq) + CaCl2(aq) -------- 2NaCl(aq) + CaCO3 (s)

Calculate the volume (in mL) of 0.100 M CaCl2 needed to produce 1.00g of CaCO (s). There is an excess of Na2CO3

Molar mass of calcium carbonate= 100.09 g/mol

volume of calcium chloride =

how do I find the volume?

White vinegar is a solution of acetic acid in water. There are two strengths of white vinegar—a 5% solution and a 10% solution. How many millilitres of each solution must be mixed to make 125 mL of a 8% vinegar solution?
