The wheels will be completely used up and  it is the limiting reactant in this case.

<h3>What is a limiting reactant?</h3>

The limiting reactant is the reactant that is completely used up in a reaction, and thus determines when the reaction stops.

  • 60 breaks will be used for 30 engines and 30 body frame
  • 80 wheels will be used for 20 engines and 20 body frame
  • 64 headlights will be used for 32 engines and 32 body frame

The wheels will be completely used up and  it is the limiting reactant in this case.

You need to dissolve CaCl2 in water to make a mixture that is 40.0% calcium chloride by mass. If the total mass of the mixture i
AlekseyPX
In order to calculate for the amount of CaCl2 and water used we need to multiply the total amount mixture to the percentage of each component. Since we are given a two component mixture CaCl2-water with 40% CaCl2 by mass, therefore we have 60% water.

Amount of CaCl2 = 0.40*(370.9) =148.36 g of CaCl2 
Amount of Water = 0.60*(370.9) = 222.54 g of Water
