How much mass is in 100 ml of water

1 answer:

8 0

Since each ml of water weights 1 g, 0.1 liters of water = 100 grams. As well, "kilo" means "thousand". So 1 kilogram (kg) = 1000 grams. This means 100 g = 0.1 kg.

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.
