  A chemical compound used in photography is silver bromide. A photographer decides to mix her own developing solution by combining silver nitrate and sodium bromide. She needs to produce 20 lb. of silver bromide to replenish her supply.

1. Make a list of the information you need to determine how much of each reactant is needed to produce 20 lb. of product.

2. Write a balanced equation for this reaction.
3. How many moles of each reactant are required to produce one mole of product?
