How many moles are in 10 grams of CaCl2?

n = 0.0901 mole

Explanation:

n = m/Mm

n = number of mole

m = number of mass

Mm = number of molar mass

Given

CaCl2

m = 10grams

Mm of CaCl2

Ca = 40.078

Cl = 35.453

CaCl2 = 40.078 + 2(35.453)

There are two atoms of Cl

= 40.078 + 70.906

= 110.984

m = 10g

n = m/Mm

Insert the values

n = 10/110.984

n = 0.0901 mole

The number of mole is 0.0901mole

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
