4) What is the mass of 25.0 moles P2O5?

Phosphorus Pentoxide. Did they tell you it is a dimer? If not, great. Just set up the equation for molar mass.

(5x16) Oxygen + (2x MOLECULAR WEIGHT phosphorus) = 1 Mole.

Now, multiply by 25.

Explanation:

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.
