# Chemistry Question Help watch

1. What amount of gas takes up 6dm^3 at 102kPa and 25 degrees? Any help would be greatly appreciated!!
2. Use the ideal gas equation, pV = nRT, you're trying to find amount (n) so divide by RT to get n=pV/RT.

You need to convert the values you have to standard units. 25°C can be converted to 298K by adding 273 . 6dm3 = 6x10-3m3 . You also need to use 102x103Pa, as the value you're given is in kPa. You know that R=8.31JK-1mol-1.

From here, you can just put the numbers in the formula.

Thank you very much! When it said 'the amount' I thought it meant the volume, but the volume had already been stated. Thank you for clearing things up for me.
