Increasing the pressure on a gas at constant temperature does what to the volume of the gas?

How many mL of 6.00 M HCl are needed to prepare 1500 mL of 0.200 M HCl solution? Reference:

What is the total pressure of a gaseous mixture that contains three gases with partial pressures of 0.845 atm, 120 torr and 210 mm Hg? Total Pressure = P1 + P2 + P3…

2500 liters of oxygen gas is produced at 1.00 atm of pressure. It is to be compressed and stored in a 20.0 liter cylinder. If temperature is constant, calculate the pressure of the oxygen in the cylinder.
