250ml of a calcium carbonate solution contains 2.5grams of CaCO3 .if 10ml of this solution is diluted to one litre , what is the concentration of the reaultant solution?

Question

Answer

The answer is 0.001 Molessolution; given data: volume of soln=250 ml mass of caco3=2.5gram molar mass of caco3=100 moles=mass/molar mass moles=2.5/100 moles=0.025 moles... therefore; molarity of soln=no.of.moles÷vol of soln in litres. (250ml----->0.25litres) molarity=0.025÷0.25 molarity=0.1moles now, 10 ml of caco3 solution dilute in to 1 litre solution so; M1×V1=M2×V2. ( therefore; V1=10ml--->0.01 litre V2=1L ; M1=0.1 moles and M2=?..)0.1×0.01=M2×1M2=0.001 moles.... and so; the concentration of resultant solution is 0.001 moles....hope u clear...!👍👍😊

Answer

Calculation of Concentration of Resultant Solution

Given Data

Volume of CaCO3 solution = 250ml

Mass of CaCO3 in solution = 2.5grams

Volume of diluted solution = 1 litre

Volume of solution taken for dilution = 10ml

Calculation

To calculate the concentration of the resultant solution, we need to first calculate the concentration of the original solution.

The concentration of the original solution can be calculated using the formula:
Concentration = (mass of solute/volume of solution) x 1000

Substituting the given values, we get:
Concentration of original solution = (2.5/250) x 1000 = 10g/L

Now, we can use the formula for dilution to calculate the concentration of the resultant solution.
The formula for dilution is:
Concentration of resultant solution = (Concentration of original solution x Volume of original solution)/(Volume of original solution + Volume of diluent)

Substituting the given values, we get:
Concentration of resultant solution = (10 x 10)/(10 + 1000) = 0.099g/L

Answer

The concentration of the resultant solution is 0.099g/L.
