# Calculate Density of Ideal Gas at 250 kPa, 4 g, 50 cm^3

• kmkindig
In summary, the formula for calculating density of an ideal gas is density = mass / volume. The mass is given as 4 g and the volume as 50 cm^3. The ideal gas constant, denoted by R, has a value of 8.314 J/mol*K. The units for pressure are typically in kilopascal (kPa), while the units for volume can vary but are often in cubic meters (m^3). This formula can be used for any type of gas as long as the conditions are within the ideal gas law. Using the given values of 250 kPa, 4 g, and 50 cm^3, the density of the ideal gas is 0.08 g/cm^3

#### kmkindig

A 100 cm^3 container has 4 g of an ideal gas in it at 250 kPa. If the volume is changed to 50 cm^3 and the temperature remains constant, what is the new density in kg/m^3.

Any help would be greatly appreciated to help me understand! Thanks

Density is mass/volume
What have you changed, what stays the same?

PV=nRT
