Astudent measures the mass of a sample of a metallic element, m. then the student heats the sample in air, where it completely reacts to form the compound mo. the student measures the mass of the compound that was formed. which of the following questions can be answered from the results of the experiment?

The question is incomplete, the complete question is;

A student measures the mass of a sample of a metallic element, M. Then the student heats the sample in air, where it completely reacts to form the compound MO. The student measures the mass of the compound that was formed. Which of the following questions can be answered from the results of the experiment?

1. What is the molar mass of M?

2. What is the empirical formula of compound?

The question that can be answered from the results of the experiment is; "What is the molar mass of M? "

By reacting the metal M with oxygen, the following reaction occurred;

M + O >MO

Since the mass of the metal sample was measured and the sample was made to react with excess oxygen as said in the question.

The molar mass of the metal can now be determined by stoichiometry since the re.action has a mole ratio of 1:1.
