Question

%w/vof 3M aqueous solution of limestone is??

Answer 1

Answer:

A percent w/v solution is calculated with the following formula using the gram as the base measure of weight (w):

% w/v = g of solute/100 mL of solution

Example 1:

Physiologic or isotonic saline is a 0.9% aqueous solution of NaCl.

0.9% saline = 0.9 g of NaCl diluted to 100 mL of deionized water,

where NaCl is the solute and deionized water is the solvent.

Example 1:

What is the % w/v of a solution that has 7.5 g of sodium chloride diluted to 100 mL with deionized water?

By definition, a percent w/v solution is the measure of weight per 100 mL. 7.5 g/100 mL = 7.5%

You can calculate this value as well:

X % = 7.5 g NaCl/100 mL of solution

X/100 = 7.5/100

Cross multiplying,

100X = 750

X = 7.5% w/v
