The value of b is how many times of the actual volume of the molecules:
4 times
5 times
3 times
2 times
The value of b is four times the actual volume of the molecules.
The volumes of gases A, B, C and D are in this ratio 1 : 2 : 2 : 4 under the same conditions of temperature and pressure.
If the volume of A is actually 5.6 dm3 at STP, calculate the number of molecules in the actual volume of D at STP (Avogadro's number is 6 x 1023).
The volume of D is four times the volume of A as given.
