1.) A sample of gas is heated from -15.0*C to 18.5*C. What was its original volume if the volume at 18.5*C is 2.75 liters?

2.) In titration of 20.00 mL H2SO4, 12.75 mL of 0.350 M NaOH were used. a.) Find the concerntration of the acid in this experiment. b.) The base solution was not standardized. How will that affect the results? How would you standardize such a solution?
