The volume of a given mass of a gas at 20°c and 75cmhg pressure is 228cmsquare3 what will be it's volume at 25°c and 76cmhg pressure?
A certain gas occupied a volume at 150cmsquare3 at an atmosphere pressure of 10suquare5nm-2 what will be its new pressure if the volume is reduced 100cmsquare3 assuming than is no change in temperature ?
A certain amount of gas occupies 5.0cdmsquare3 at 2ATM and 10°c calculate the number of moles present R=0.82Atmdmsquare3 mole
It's difficult to answer multiple questions on one post. Here is the first and second one. For #1, you must mean 400 cc.
Use (V1/T1/) = (V2/T2)
Remember T1 and T2 must be in kelvin.

#2. I have no idea what 228 cmsquare3 means. You probably meant 228 cc or 228 cm^3.
Use (P1V1/T1) = (P2V2/T2)
Remember to convert T2 and T1 to kelvin.
Post your work if you get stuck.
