When you have a substance made of some molecules you need to know each mass, in this case, CaCO3 has one atom of Ca, one atom of C and three of O.

Ca: 40.078 grams per mol

C: 12.011 grams per mol

O: 15.999 gramps per mol

[Ca+C+(O*3)]= 1 mol

[40.078 + 12.011 + (3*15.999)]=100.086 grams per mol

Now, they ask you about 5.66 moles. You could do a cross multiplication and say:

1mol-------100.086 grams

5.66mol----X= 566,48676 grams = 566,5 grams

The number of grams in 5.66 mol of [tex]\bold{CaCo_3}[/tex] is 566.5 grams.

How can we calculate the mass of the compound?

First, we have to find the molar mass of the compound. For this, we multiply each term with its molar mass and then sum all of it.

The molar mass of calcium is 40, carbon is 12, and oxygen is 16.

[tex]40.08\times1+12\times1+16\times3 = 100.1 g[/tex]

The molar mass of the compound is 100.1 grams.

Hence, the mass of the compound is :

[tex]5.66\times100.1 = 566.6\; grams[/tex].
