Question

a solution contains 50ml of alcohol mixed with 150ml of water find the concentration of solution.

Answer 1

alcohol+water=alcohol+hydrogen

Answer 2

Required Answer:

Given:

• Volume of alcohol ( solute ) = 50 ml

• Volume of water ( solvent ) = 150ml

To calculate:

• Concentration of solution.

Calculation:

We know that,

• Concentration of solution = ( Volume of solute/Volume of solution ) × 100

Let us calculate the volume of solution firstly:

• Volume of solution = Volume of solute + Volume of solvent

→ Volume of solution = ( 50 + 150 )ml

→ Volume of solution = 200ml

Now,

• Concentration of solution = ( Volume of solute/Volume of solution ) × 100

Substituting values-

→ Concentration of solution = ( 50/200 ) × 100

→ Concentration of solution = ( 50 × 100 /200 )

→ Concentration of solution = ( 5000 /200 )

→ Concentration of solution = ( 50 /2 )

→ Concentration of solution = 25%
