Consider the equation for weight:

W=mg

W is the weight, m is the mass, and g is the acceleration due to gravity.

Therefore, to calculate the weight of an object, just multiply its mass by the acc. due to gravity of the location.

The acc. due to gravity on Earth is approximately 9.81 ms^-2, note that this number may change from place to place, for example, the acc. due to gravity on moon is only 1/6 of Earth's. (Sometimes the question provides g as 10, so make sure you check the instructions before!)

W = 1.5 x 9.81

   = 14.715N (≈14.7N)

Therefore, the answer to this question is the last option (or D), 14.7N.

What is the difference between inert and stable?
Katena32 [7]
Inert means that the substance did not have a tendency to react at all, while stable means that the substance has reached a chemical state in which it is not likely to react. Stability is easier to overcome than inertness.
