Question

What volume of 1.25 M sodium hydroxide (NaOH) solution can be prepared using 60.0 g of sodium hydroxide? (The mass of one mole of NaOH is 40.0 g.)

0.667 L
0.833 L
1.20 L
1.88L

Answer 1

The answer is

1.20 L

Step-by-step explanation:

Since the concentration , mass and molar mass of NaOH has been given we use the formula

`C = (m)/(M * v)`

To find the volume

where

C is the concentration

m is the mass

M is the molar mass

v is the volume

Making volume the subject we have

`v = (m)/(C * M)`

From the question

C = 1.25 M

m = 60 g

M = 40.0 g/mol

Substitute the values into the above formula and solve for the volume

We have

`v = (60)/(1.25 * 40) \\ v = (60)/(50) \\ v = (6)/(5)`

We have the final answer as

Volume = 1.20 L
