Answer:
There is 45 ml HCI in the bottle.
Step-by-step 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
[tex]=\frac{75\times 60}{100}[/tex]
[tex]=\frac{4500}{100}[/tex]
[tex]= 45 \text{ ml}[/tex]
