Explanation:
Gasoline has many different types of hydrocarbons. This makes it a mixture.
Another element maybe BeCa if you combine them
(B) Because acceleration is change of speed over time.
Number of moles = mass of product / molecular mass
=mass of product (MgO) / 40.3
Since the mass of MgO is not given in the question, the correct answer choice cannot be given. However, proceeding witht eh above formula will enable you to find the correct number of moles given the mass of MgO.
