Answer:
1.4200 g
Explanation:
The chlorine gas has a molecular formula Cl2. In table periodic, the molar mass of one atom of chlorine is 35.5 g/mol, so the molar mass of Cl2 is 71 g/mol.
Molar mass, mass and number of moles are related by the equation below:

Where n is the number of moles, m is the mass, and MM is the molar mass of the compound.
So, for 0.0200 moles of Cl2 produced:

m = 71x0.0200
m = 1.4200
Answer:

Explanation:
Hello,
In this case, since the density is defined as the degree of compactness of a substance and it mathematically defined as the ratio of the mass and volume:

By knowing that its density is 1.11 g/mL, the mass in 366 mL is:
