Question

Chemistry Numericals, can anyone solve all of emm??
The torr (symbol: Torr) is a unit of pressure based on an absolute scale, defined as
exactly 1760 of a standard atmosphere (101325 Pa). ... Thus one torr is exactly
101325760 pascals @ 133.32 Pa). |
Numericals:
1) What volume will 50 ml of a gas at 725 Torrs occupy if the pressure is increased to 760
Torrs?
2) If the volume of a gas, at constant temperature, changes from 200 ml to 500 ml, the
pressure on the gas must have changed from 400 Torrs to
a) What do you predict will happen to pressure? (increase/decrease)
3). If a gas sample in a balloon had a volume of 100 ml and a pressure of 3 atm. It was
then compressed to a pressure of 10 atm, what would be its volume?
4) I have added 15L of air to a balloon at sea level(1.Oatm) If I take the balloon with me to
Denver where the air pressure is 0.85 atm,what will the new volume of the balloon be?
5)A container holds 50.0 mL of nitrogen at 25° C and a pressure of 736 mm Hg. What will
be its volume if the temperature increases by 35° C?
6) A sample of hydrogen has an initial temperature of 50.° C. When the temperature is
lowered to -5.0° C, the volume of hydrogen becomes 212 cm'. What was the initial
volume of the hydrogen in dm?
7) A sample of helium has a volume of 521 dm3 at a pressure of 75 cm Hg and a temperature
of 18° C. When the temperature is increased to 23° C, what is the volume of the helium?​
