What is the molarity of a solution of 73 g of HCL in 2 liters of water?
Molarity = moles of solute/Liters of solutionSo, get moles HCl.73 grams HCl (1 mole HCl/36.458)= 2.00 moles HCl---------------------------Molarity = 2.00 moles HCl/2 Liters= 1 M HCl=======
How many grams of zinc can react with 225ml of 0.200 m HCl solution?
Balanced equation first.Zn + 2HCl - ZnCl2 + H2now we find moles HCl by....Molarity = moles of solute/Liters of solution ( 225 ml = 0.225 Liters )0.200 M HCl = X moles/0.225 Liters= 0.045 moles HCl================Now, drive reaction backwards.0.045 moles HCl (1 mole Zn/2 mole HCl)(65.41 grams/1 mole Zn)= 1.47 grams zinc reacted----------------------------------
How many moles of hcl are needed to react with 4 moles of cuo?
4 mole cuO X 2/1 = 8 mole Hcl
How many moles of CuO are needed to react with 4 moles of HCL?
4 mole cuO X 2/1 = 8 mole Hcl
What is the limiting reactant of 60.0grams of aluminum present when a reaction with 25grams of hydrochloric acid occurs?
This reaction?2Al + 6HCl -> 2AlCl3 + 3H2Get moles species.60.0 grams Al (1 mole Al/26.98 grams) = 2.2239 mole Al==================================================================================2.2239 moles Al (6 mole HCl/2 mole Al)= 6.6717 moles HCl-------------------------0.68572 moles HCl (2 mole Al/6 mole HCl)= 0.22857 mole Al------------------------As you see you have way more moles aluminum than you need, but. you do not have nearly enough HCl to meet the mole burden.Hydrochloric acid limits this reaction.

How many moles of HCl and needed to react 2.4 moles of Al?
Al+HCl===> AlCl3+H2 Is the reaction. You need &.2 moles of HCl.
How many grams of sodium carbonate is needed to react with 18.1 ml of 0.23M HCL?
Balanced equation always first!! Na2CO3 + 2HCl -> 2NaCl + CO2 + H2O Find moles HCl by---Molarity = moles of solute/Liters of solution (18.1 ml = 0.0181 L) 0.23 M HCl = moles HCl/0.0181 liters = 0.004163 moles HCl Drive back against sodium carbonate stoichometrically 0.004163 moles HCl (1 mole Na2CO3/2 mole HCl)(105.99 grams/1 mole Na2CO3) = 0.22 grams Na2CO3 needed --------------------------------------------
How many millimeters of a 2 Molar solution of hydrochloric acid are needed to completely react with 75 grams of iron sulfide?
FeS + 2HCl >> FeCl2 + H2S 75 grams FeS (1mole FeS/87.92 grams)(2 mole HCl/1 mole FeS) = 1.71 moles HCl 2 Molar HCl = 1.71 moles HCl/Liters = 0.855 Liters HCl, or as asked for; 855 milliliters of hydrochloric acid needed
How many grams of hydrochloric acid are reacted when 1.80 mol of zinc is reacted with 7.10 mol of hydrochloric acid?
A lot of that hydrochloric acrid is excess and some grams will not react, I think. Balanced equation first. Zn + 2HCl -> ZnCl2 + H2 Check to make sure of limiting reactant; I suspect zinc. 1.80 moles Zn (2 mole HCl/1 mole Zn) = 3.60 moles HCl You have a lot more than that, Zn limits and will drive the reaction 1.80 moles Zn (2 moles HCl/1 mole Zn)(36.458 grams/1 mole HCl) = 131 grams of hydrochloric acid reacted with that Zinc amount ----------------------------------------------------------------------------------
How would you find the answer to this question How many moles of HCl can be formed when moles of hydrogen gas react with chlorine?
For each mole of hydrogen gas (H2) reacting with chlorine gas (Cl2), you will get 2 moles of HCl. H2 + Cl2 = 2 HCl
How many moles of CuO are needed to react with 4 moles of HCL?
4 mole cuO X 2/1 = 8 mole Hcl
How many moles of hcl are needed to react with 4 moles of cuo?
4 mole cuO X 2/1 = 8 mole Hcl
