<u>Answer:</u> The density of sugar is
<u>Explanation:</u>
To calculate the density of a substance, we use the equation:
We are given:
Mass of sugar = 316 g
Volume of box =
Putting values in above equation, we get:
Hence, the density of sugar is

<u>Answer:</u> The mass of manganese(III) oxide produced is 113.03 g
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of zinc = 46.8 g
Molar mass of zinc = 65.38 g/mol
Plugging values in equation 1:
The given chemical equation follows:
By the stoichiometry of the reaction:
If 1 mole of zinc produces 1 mole of manganese(III) oxide
So, 0.716 moles of zinc will produce = of manganese(III) oxide
Molar mass of manganese(III) oxide = 157.87 g/mol
Plugging values in equation 1:
Hence, the mass of manganese(III) oxide produced is 113.03 g
