Answer to Question #167674 in Organic Chemistry for Ashini

Question

How to calculate calcium concentration in toothpaste. Please give me a method..

Answer 1

Minerals can be found in your toothpaste, and they're there for good reason. Calcium and phosphorous (in the form of phosphate), along with fluoride, are included in toothpaste because they play a key role in keeping your teeth from becoming soft and yucky, which makes it easy for cavities .

First we calculate the moles of Ca in toothpastes then we can find concentration ( in terms of molarity ) and then we can convert mol / liter into g / L by multiplying molar mass of Calcium .
