Achemist measures the amount of oxygen gas produced during an experiment. she finds that 4.87 g of oxygen gas is produced. calculate the number of moles of oxygen gas produced. be sure your answer has the correct number of significant digits.

0.152 moles

Explanation:

Given that:

The mass of the oxygen gas produced = 4.87 g

Also, The molar mass of oxygen gas, = = 32 g/mol

The formula for the calculation of moles is shown below:

Thus,

Both given values and the answer is in 3 significant digits.
