Question

calculate the concentration of solution which contain 2.5 gram of salt dissolved in 50 gram of water plzz give me 100 % right answer ❤️ ​

Answer 1

given the mass of solute (salt) = 2.5 g

and mass of solvent (water) = 50g

as we know that mass of solution = mass of solute + mass of solvent

= 2.5 + 50

= 52.5g

concentration of the solution = (mass of solute/mass of solution) × 100

= (2.5/52.5) × 100

= 250/52.5

= 4.76% (approximately)

Answer 2

Given the mass of solute (salt) = 2.5 g and mass of solvent (water) = 50g

As we know that mass of solution = mass of solute + mass of solvent

s we know that mass of solution = mass of solute + mass of solvent= 2.5 + 50

s we know that mass of solution = mass of solute + mass of solvent= 2.5 + 50= 52.5g

Concentration of the solution = (mass of solute/mass of solution) × 100

oncentration of the solution = (mass of solute/mass of solution) × 100= (2.5/52.5) × 100

oncentration of the solution = (mass of solute/mass of solution) × 100= (2.5/52.5) × 100= 250/52.5

oncentration of the solution = (mass of solute/mass of solution) × 100= (2.5/52.5) × 100= 250/52.5= 4.76% (approximately)

Hope this helped....
