Reorder the following steps in order to answer the following question:
How many liters of O2 gas are needed to react with 3.46 g of H2 to form water?
2 H2 + O2 --> 2 H2O
Convert grams of H2 to mole using molar mass
Convert moles of H2 to moles of O2 using balanced equation
Use PV = nRT to solve for liters of O2
Match the following conversion factors with the proper unit
Liters of a gas at STP
22.4
Liters of a gas NOT at STP
PV = nRT
atoms/molecules/particles
6.02 x 1023
grams
molar mass
Liters of a solution
M = mol/L
Drag the following labels to show the equation for percent yield.
Reorder the following steps to solve the following question:
How many atoms of Cu would be produced from a 65.0mL of a 4.00M Copper (II) Chloride solution?
2 Al + 3 CuCl2 --> 3 Cu + 2 AlCl3
Convert 65.0mL to L
Solve for mol of CuCl2 using M = Lmol
Convert mol of CuCl2 to mol of Cu using balanced equation
Convert mol of Cu to atoms using 6.02 x 1023
