Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Question

Solve the following: example
9)
10)
How many grams are in 4.5 moles of sodium fluoride, NaF?
(molar mass of NaF is 22.99 + 19.00 = 41.99 g/ mole)
4.5 moles x 41.99 grams = 188.955 g NaF =
1 mole
How many moles are in 98.3 grams of aluminum hydroxide, Al(OH)3?
(molar mass of Al(OH)3 is 26.98 + (3 x 16.00) + (3 x 1.01) = 78.01 g/mole)
1.2601 moles Al(OH)3 = 1.26 moles Al(OH)3
