Sam works at the Salem Sandwich Shoppe. Sam expected a big day on Tuesday, so he ordered the following:
5 pounds of bologna (10 slices per pound)
4 pounds of cheese (16 slices per pound)
5 packages of buns (12 buns per package)
How many sandwiches can Sam make?
1 slice bologna + 1 slice cheese on 1 bun
26.28g Sr 1 mole Sr 0.30 moles Sr
39.95g Br21 mole Br2 0.25 moles Br2
Which reactant is the limiting reagent?
The Br2 will run out first because there are less moles of Br2 than Sr.
Now calculate the mass of product using the number of moles of the limiting reagent.
0.25moles Br21 mole SrBr2 0.25moles SrBr2
1 mole Br2
0.25moles SrBr2247.4g SrBr2 61.85g SrBr2
1 mole SrBr2
How many grams of sodium chloride will be produced if 0.93g of sodium oxide reacts with 1.67g of barium chloride?
Write a balanced equation.
Convert both grams to moles.
Determine the limiting reagent.
Use the limiting reagent calculate the mass of NaCl.
