Answer:
0.9375 mole
Step-by-step explanation:
Data obtained from the question include:
Volume of solution = 1.50L
Molarity of NaCl = 0.625 M
Mole of NaCl =..?
The molarity of a solution is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is represented as:
Molarity = mole /Volume
With the above equation, the number of mole of NaCl in the solution can be obtained as follow:
0.625 = mole / 1.5
Cross multiply to express in linear form
Mole = 0.625 x 1.5
Mole = 0.9375 mole
Therefore, 0.9375 mole of NaCl is present in the solution.
