Sweet_03:
aha! nd how do i know the number ?
By the way , yur right ! its is fluorine but i nvr knew why ?
ok thank you astar : ) that made it clearer
mousa:
The density of ice is 1.00 g cm–3.
What is the volume of steam produced when 1.00 cm3 of ice is heated to 323 °C (596 K) at a
pressure of one atmosphere (101 kPa)?
[1 mol of a gas occupies 24.0 dm3 at 25 °C (298 K) and one atmosphere.]
A 0.267 dm3 B 1.33 dm3 C 2.67 dm3 D 48.0 dm

anyone else???
Sweet_03:
the dude ,
since yur doing Physics Edexcel !i jst wana ask yu , is momentum in the new syllabus ?

ig of gas =1/18mol sin 1 mol water weighs 18g
so 1g gas occupies 24/18dm3
V1/T1=V2/T2 so V2=V1*T2/T1=24/18*(323+273)/(25+273)=2.585dm3
For some reason I put 1/18 instead 24/18
