I’m not really sure what the qn is asking for but if i’m not wrong it should be ‘1’ for each blank!
The temp is 0.002448 of the equation
It would be 35g because you can break the ice chunk into as many pieces as you want when you combine them back together you'll always get the same weight
We can use the ideal gas law equation to find the volume of the gas.
PV = nRT
P - pressure - 400 kPa
V - volume
n - number of moles - 4.00 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 300.0 K
substituting these values in the equation
400 000 Pa x V = 4.00 mol x 8.314 Jmol⁻¹K⁻¹ x 300.0 K
V = 24.9 dm³
Volume is 24.9 dm³
