Question

To make a saturated solution 36g of sodium chloride is dissolved in 100g of water at 293 K . Find the concentration at this temperature.

Answer 1

first add the solution

which is in grams 100+36 = 136

now subtract it by 293k

u will get 157

so the answer is 157

see it is very easy

just u need to add and subtract

if u like this answer mark it as the brainlly

and don't forget to follow me

Answer 2

Required Answer:

Given:

• Mass of the sodium chloride (solute) = 36 g

• Mass of the water (solvent) = 100 g

To calculate:

• Concentration at 29K temperature.

Calculation:

We know that,

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

We need to calculate the mass of the solution first,

→ Mass of the solution = Mass of solute + Mass of solvent

→ Mass of the solution = ( 36 + 100 ) g

→ Mass of the solution = 136g

_________

Now,

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

Substituting values:

→ Concentration of solution = ( 36/136 ) × 100

→ Concentration of solution = ( 36 × 100 /136 )

→ Concentration of solution = ( 3600 /136 )

→ Concentration of solution = 26.47%
