A student is asked how many moles are in 3 grams of Hydrogen gas. The student answers that there are 3 moles of Hydrogen gas in 3 grams of Hydrogen gas.
Construct a response to each of the following prompts:

Explain why 3 grams does not equal 3 moles

Hi how are you doing today Jasmine

The question is incomplete, the complete question is;

. A chemist determined by measurements that 0.015 moles of hydrogen chloride participate in a chemical reaction. Calculate the mass of hydrogen chloride that participates Round your answer to 2 significant digits. x S. ?

0.54 g

Explanation:

Recall that;

Number of moles = mass/molar mass

Molar mass of HCl =36.5 g/mol

Mass= number of moles × molar mass

Mass= 0.015 moles × 36 g/mol

Mass= 0.54 g
