Determine the mass in grams of each of the following:

A. 1.25 mol [tex]CaF_{2}[/tex]

B. 3.4 mol ([tex]NH_{4}[/tex])[tex]_{2}SO_{4}[/tex]

Respuesta :

We know, Given mass = Molar mass * Number of moles.

A.) 1.25 mol CaF

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!
