How many grams of F are in 365 g CaF2 ?

177 grams

Explanation:

moles of CaF₂ = = = 4.67949

moles of F-atom = 2×moles of CaF₂ = 2×4.67949 = 9.35898

(mol)×(molar mass)= 9.35898×19 = 177.82062

Therefore, 177 grams of F are in the mixture.

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.
