Answer:
1.60 g
Explanation:
A chemist determines by measurements that 0.0500 moles of oxygen gas, that is, O₂, participate in a chemical reaction. The molar mass of oxygen is 32.00 g/mol. We can find the mass corresponding to 0.0500 moles using the following expression.
m = n × M
where
m is the mass
n are the moles
M is the molar mass
m = n × M
m = 0.0500 mol × 32.00 g/mol
m = 1.60 g
