Determine the mass in grams of each of the following:
nekit [7.7K]
We know, Given mass = Molar mass * Number of moles.

A.) <span>1.25 mol CaF</span>₂

Number of moles = 1.25
Molar mass = 78

So, Mass = 78 * 1.25 = 97.5 g

B.) 3.4 mol (NH₄)₂SO₄

Number of moles = 3.4
Molar mass = 132

Mass = 3.4 * 132 = 448.8 g

Hope this helps!

The reaction is not balanced

<h3>Further explanation</h3>

Given

Reaction

2Fe(s)+3O₂(g)⇒2Fe₂O₃(s)

Required

The number of atoms

Solution

In a balanced chemical equation, the number of atoms in the compound that reacts (the reactants and products) will have the same number

Reactants : Fe(s)+O₂(g)

Fe = 2 atoms

O = 3 x 2 = 6 atoms

Products : Fe₂O₃(s)

Fe = 2 x 2 = 4 atoms

O = 2 x 3 = 6 atoms

The reaction is not balanced because the number of Fe atoms is not the same

The balanced reaction should be:

4Fe(s)+3O₂(g)⇒2Fe₂O₃(s)
