(a) Calculate the moles of H3PO4 if there are 9.40 grams of water.
(b) Calculate the grams of H3PO4 if there are 0.730 moles of water.
(c) Calculate the grams of H3PO4 if there are 4.57 grams of tetraphosphorus decoxide.
(d) Calculate the moles of tetraphosphorus decoxide if there are 0.667 moles of water.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
