The molarity of the solution is 0.1625M.
<h3>What do you meant by Molarity</h3>
Molarity is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of solute per litres of a solution .
Molarity → no of moles / Volume (L)
SI unit of Molarity is M or mol/ L
We have given here the mass of solution is 3.10×10²g .
molality of the solution is 0.125m
Molality → no of moles / mass in kg
→ 0.125×3.10×10²/ 1000
→ no.of moles = 0.0162
For molarity we can assume volume as 1000 ml .
Molarity = 0.0162×1000/ 100
Molarity →0.162 M.
So, the molarity of solution will be 0.162M.

Explanation:
One mole of NaCl weighs 58.44 grams
Therefore 1L of one mole of NaCl contains 58.44 grams
1L of 0.2m NaCl contains 58.44x0.2 = 11.69grams
300mL of 0.2m NaCl contains 11.69x0.3 = 3.51 grams
Hey there !
Molar mass KOH = <span>56.1056 g/mol
1) Number of moles :
n = m / mm
n = 25.4 / </span><span>56.1056
n =0.452 moles
Volume in liters :
985 mL / 1000 => 0.985 L
Therefore:
M = n / V
M = </span>0.452 / 0.985
=> 0.458 M
