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

1g of gas =1/18mol since 1 mol water weighs 18g
so 1g gas occupies 24/18dm3
V1/T1=V2/T2 so V2=V1*T2/T1=1/18*(323+273)/(25+273)=0.1119dm3

Thanks for the reply but your answer sir is non of the choices given plus we are supposed to use PV=nRT
