A .662 g sample of metal, M, reacts completely with sulfuric acid according to M(s) + H2SO4(aq) —> MSO4(aq) + H2(g)

A volume of 301 mL of hydrogen is collected over water; the water level in the collecting vessel is the same as the outside level. Atmospheric pressure is 756.0 torr, and the temperature is 25°C. The vapor pressure of the water at 25°C is 23.8 torr. Calculate the molar mass of the metal.

im not exactly sure but i think its b!

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.
