Convert the dm to cm. find the mass of helium at the low temp, then find the moles which should be 1.46e7. Then use pV=nrt make sure p is in pascals. R is the gas constant and t is the temperature (298K).

you can help me instead ;P Make sure you're looking up the right density at the right temperature - it wasn't very easy to find. And check units. convert everything to meters cubed, use the formula density = mass/ volume.
10. Oh and done gold, it's ridiculous, you need to find a medal which they all won and then find the recipient of it in 2010.
