E ground pushes you forward. But that interaction is friction. Reduce friction and it doesn't matter how strong your legs are, the surface is incapable of pushing you accordingly. The coefficient of static friction is very low so it is easy to slide your foot rather than push.
Answer:
100.8 dm3
Explanation:
mol= volume
_______
molar volume
Simply transpose the formula
volume=mol x molar volume
4.5molx22.4 mol/dm3
= 100.8dm3
NB STP=22.4 dm3 or 22400 cm3
