<span>The answer is 62 u. The molecular mass of a molecule (Mr) is the sum of atomic masses (Ar) of its elements. Ar(Na) = 23 u. Ar(O) = 16 u. Therefore, the molecular mass of sodium oxide is 62 u: Mr(Na2O) = 2 * Ar(Na) + Ar(O) = 2 * 23 u + 16 u = 46 + 16 = 62 u.</span>

Using conservation of momentum, we can solve for the force that the air bag exerts on the person.
Recall the equation for momentum (p):

We can solve for total momentum, then divide by out time interval. This gets us:
F = 4800N
