Use the appropriate gas law and units to calculate the pressure exerted on a 10.0 L container with only 5.0 g of CO2(g) at a temperature of 25 oC. R = 0.08206 (atm•L)/(mol•K)

How many moles of calcium sulfate are contained in 47.6 g CaSO4?

A 42.1 g piece of metal was heated up to 97.4 oC and then dropped into a beaker containing 63.0 g of water at 22.0 oC. When the water and metal come to thermal equilibrium, the temperature is 30.10 oC. What is the specific heat capacity of the metal? Specific heat capacity of the water is 4.184 J/(g• oC)
