Question

A 0.680 m ca(oh)2 solution was prepared by dissolving 55.0 grams of ca(oh)2 in enough water. what is the total volume of the solution formed?

Answer 1

1.09 Liters

The total volume of the solution formed is 1.093 L

We know that,

Ca(OH)2 = 74 g/mole

n = 55/74 = 0.743 mole

M = n/V

where,

M = mass of the solution

n = number of moles

V = Volume of solution

0.680 = 0.743 / V

V = 0.743/0.680

= 1.093 L

= 1093 ml

Therefore, the total volume of the solution formed is 1.093 L

What is molarity?

• The amount of a substance in a specific volume of solution is known as its molarity (M).
• The number of moles of a solute per liter of a solution is known as molarity.
• The molar concentration of a solution is another name for molarity.

What is the molarity unit?

• Molarity is measured in mol/L.
• The molarity, which is given as moles/liter, is the quantity of moles of solute per liter of the solution.

Example of molarity:

• The moles of solute per liter of solution is measured as molarity.
• For instance, when table salt is dissolved in water, water serves as both the solution and the solute.
• Sodium chloride weights 58.44 grams per mole.
• One molar solution, or 1M, is created by dissolving 58.44 grams of sodium chloride in one liter of water.
