Question

Calculate the molarity of Na2SO3. in the solution prepared by dissolving its 16g in enough water in from 700ml of the solution. answer this​

Answer 1

Answer:number of moles of Na2SO3÷700×1000 is your answer

Explanation:

Answer 2

Ok so we know

Molarity = no. of moles/vol. of solution

So we first calculate no. Of moles of Na2SO3 we have,

n = given mass/ Molar mass

= 16g/126g

Vol. Of solution = 700/1000 L

Putting in the formula

M = 16 x 1000/(126 x 700)

= 0.18 approx

The calculation part is not good i know .. but if u r aware of the formula it's very easy to solve.. ask for doubts if any

I hope it helps..
