Answer : The mass of calcium chloride is, 116.84 grams
Solution : Given,
Molar mass of calcium chloride,
= 110.98 g/mole
Number of molecules of calcium chloride = 
As we know that,
1 mole of calcium chloride contains
molecules of calcium chloride
or,
1 mole of calcium chloride contains 110.98 grams of calcium chloride
Or, we can say that
As,
molecules of calcium chloride present in 110.98 grams of calcium chloride
So,
molecules of calcium chloride present in
of calcium chloride
Therefore, the mass of calcium chloride is, 116.84 grams
Answer:
A)P5010
Explanation:
Penta- means 5 and deca/deco- means 10
<span>Total mass = 2.75g
Mass % of Mg = 1.0g x 100/2.75g = 36.36 %
Mass % of O = 1.75g x 100/2.75g = 63.64 %
Mol of Mg = 36.36/24 = 1.515
Mol of O = 63.64/16 = 3.977
Ratio of Mol of Mg and O in the substance = (1.515 : 3.977) x 2 = 3 : 8
The empirical formula of substance is Mg3O8</span>
