Question is incomplete, complete question is :
A fixed quantity of gas at 21°C exhibits a pressure of 758 torr and occupies a volume of 5.42 L .
Calculate the volume the gas will occupy if the pressure is increased to 1.89 atm while the temperature is held constant.
Answer:
The final volume of the gas will be 2.86 L.
Explanation:
initial pressure of the gas =
initial volume of the gas =
Final pressure of the gas =
Final volume of the gas =
Applying Boyle's law;
( at constant temperature)
The final volume of the gas will be 2.86 L.
Solids have a definite shape and definite volume. This means that the shape of the material does not change, and it can't be compressed.
