Answer:
0.193 L
Explanation:
Another way of writing the question would be: What volume of a 7.5 M Sodium Bromide solution would contain 1.45 moles.
To answer that we can use the <em>definition of molarity</em>:
- Molarity = moles / liters
We <u>input the given data</u>:
- 7.5 M = 1.45 moles / liters
And <u>calculate how many liters are required</u>:
- 1.45 mol / 7.5 M = 0.193 L
