application of ideal gas law

Convert the following pressure into atmospheres.
781 torr
781 mm Hg

A 1.04-L sample of gas at 759 mm Hg pressure is expanded until its volume is 2.24 L. What will be the pressure in the expnaded gas sample at a constant temperature.

At conditions of constant temperature and pressure, the volume of a sample of ideal gas is proportional to the number of moles of gas present.

If 3.25 mol of argon gas occupies a volume of 100L at a particular temperature and pressure, what volume does 14.15 mol of argon occupy under the same conditions.

Suppose a 24.3-ml sample of helium gas at 25 degrees C and 1.01 atm is heated to 50 degrees C and compressed to a volume of 15.2 ml. What will the pressure of the sample be.

Please see the attached file.

convert the following pressure into atmospheres.

1. 1 torr = 1 mmHg
1 atm = 760 mmHg
So 1 mmHg = atm
Then 781 torr = 781 mmHg = 781 * atm = 1.0276 atm

2. A 1.04-L sample of gas at 759 mm Hg pressure is expanded until its volume is 2.24 L. What will be the pressure in the expnaded gas sample at ...
