Chemistry

At 1.00 atm pressure and 273 K one mole of gas should occupy22.4 L. What volume would one mole of gas occupy at 21oC and 1.00 atm?

In the Molar Mass of Magnesium experiment:

a) At the end of the reaction, the temperature was 21.5oC (294.65 K), 99.2 mL of gas were formed, and thepressure was 1.00 atm in the gas syringe. The Gas Constant has avalue of 0.08206 L atm/ (mol K) (Pay attention to theseunits!!!).

How many moles of Mg reacted?

b) What Molar Mass did you calculate for Mg?
