A solution is prepared by dissolving 10g of naoh in 100ml of solution . its molarity is
Answers
Answer: Molarity is 0.25 M
Explanation: Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Formula used :
where,
n= moles of solute
= Volume of solution in ml
Now put all the given values in the formula of molarity, we get
Therefore, the molarity of solution will be 0.25 mole/L.
Answer:
Answer: Molarity is 0.25 M
Explanation: Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Formula used :
Molarity=\frac{n\times 1000}{V_s}Molarity=
V
s
n×1000
where,
n= moles of solute
Moles=\frac{\text{Given mass of solute}}{\text{Molar mass of solute}}=\frac{10}{40}=0.25molesMoles=
Molar mass of solute
Given mass of solute
=
40
10
=0.25moles
V_sV
s
= Volume of solution in ml
Now put all the given values in the formula of molarity, we get
Molarity=\frac{0.25moles\times 1000}{100ml}=2.5mole/LMolarity=
100ml
0.25moles×1000
=2.5mole/L
Therefore, the molarity of solution will be 0.25 mole/L.
