Question

How much HCI (hydrochloric acid) is in a 60-milliliter bottle that is marked 75% HCI?

Answer 1

There is 45 ml HCI in the bottle.

Explanation:

Given,

Total volume of the bottle = 60 ml,

Also, the bottle is marked 75% HCI,

Hence, the volume of the HCl in the bottle

= 75% of the volume of the bottle

= 75% of 60

`=(75* 60)/(100)`

`=(4500)/(100)`

`= 45 \text{ ml}`
