Ideal gas equation is PV = nRT, at STP, temperature is equal to 250C, pressure is = 1 atm.
then V = nRT/V, where V is proportional to temperature (T).
at STP temperature is 250C, then volume occupied by one mole gas is equal to 22.4L.
but given condition Temperature = 300C, that means temperature increased.
if temperature increases volume also increased.
volume is higher than the volume observed at STP, due the temperature is increased (or temperature is more that STP temperature.)
Molar volume (V/n) can be calculated and measured for any set of conditions. At 30.0°C and...

waa r the accepted value at SIF, and the perce REVIEW QUESTIONS MPC, rather than 45 ml of Me would have made any difference in the amount of oxygen was collected? Explain why or why not In this experiment, some oxy en gas will dissolve in water How will this affect the molar volume calculated? Would the molar volume be too high or too low In Step 1, if the outside of flask was wet when you weighed it, how...
The density of hydrogen of hydrogen gas, H:8) at STP has been measured to be 0.08988 Calculate the molar volume of this gas at STP (b) Calculate the per cent deviation of this value from the molar volume of an ideal gas, 22.414 L (c) Assuming Charles' law to be valid, calculate the molar volume of this gas at 1,000 atm and 25.00*C. (d) Assuming the molecules of the gas "occupy" equal fractions of the total gas volume, and that...
chpt.9 pg 11: Pressure and temperature affect the amount of space between gas molecules, which affects the volume and, therefore, the density of the gas since density=massvolume The molar mass of a substance, however, is a constant and can be used to identify an unknown gas sample. Molar mass is found by dividing the mass of a sample (in grams) by the number of moles in that sample. The number of moles of gas can be calculated using the ideal...
