Momentum of a body is calculated by multiplying the mass of a moving body with its velocity. When a body is at rest it has zero momentum since the velocity is also zero.
In this case the momentum of the canoe will be;
38 kg × 2.2 m/s = 83.6 kgm/s
Therefore, the correct answer is 83.6 kg m/s

1 atm is equivalent to 760 torr.
To express 0.905 atm in torr, all you have to do is cross multiplication as follows:
1 atm ................> 760 torr
0.905 atm .........> ?? torr
pressure = (0.905 * 760) / (1)
pressure = 687.8 torr
