If 32.146g of mgso4 is added to enough water to make 100.00ml solution, what is the molarity of mgsoa? 1) 2.6706 m 2) 3.7445m 3) 0.037445 4) 0.0026706 m 5) 3869.4 m

Aroom with dimensions 7.00m×8.00m×2.50m is to be filled with pure oxygen at 22.0∘c and 1.00 atm. the molar mass of oxygen is 32.0 g/mol. how many moles noxygen of oxygen are required to fill the room? what is the mass moxygen of this oxygen?

Ab c or d ? i’m not sure what the answer is

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
