Question

calculate the amount of NaOH required to prepare 100ml of 0.1N NaOH solution​

Answer 1

Solution:

Given,

Na = 23 g

O = 16 g

H = 1 g

To make 1N NaOH solution = dissolve 40 grams of NaOH in 1L of water.

To make 0.1N NaOH solution = dissolve 40 grams of NaOH in 1L of water.

To make 0.1N NaOH solution in 100 ml of water:

1000 ml of water = 4 g of NaOH

1 ml of water = (4/1000) g of NaOH

For 100 ml of water = (4/1000) × 100 = 0.4 g of NaOH.

Thus, the amount of NaOH required to prepare 100ml of 0.1N NaOH solution is 0.4 g of NaOH.

Answer 2

Answer:

The amount of $NaOH$ required to prepare 100ml of 0.1N $NaOH$solution is 0.4 g of $NaOH$.

Explanation:

Given:

$Na = 23 g$, $O = 16 g$ and $H = 1 g$

To calculate the amount of NaOH required to prepare 100ml of 0.1N $NaOH$ solution.

​

To make a 1N $NaOH$ solution = dissolve 40 grams of $NaOH$ in 1L of water.

To make a 0.1N $NaOH$ solution = dissolve 40 grams of $NaOH$ in 1L of water.

To make 0.1N $NaOH$solution in 100 ml of water:

then, 1000 ml of water  is equal to 4 g of $NaOH$

1 ml of water $= (4/1000) g$ of $NaOH$

For 100 ml of water $= (4/1000) * 100$

$= 0.4 g$ of $NaOH$.

Thus, the amount of $NaOH$ required to prepare 100ml of 0.1N $NaOH$solution is 0.4 g of $NaOH$.
