When ur talking abt acids why do we also talk about h+ ions and oh- ions

Like where did they come from
Acids are substances that contain hydrogen ions in solution, the more hydrogen ions the stronger the acid.
When acids are added to water, they form positively charged hydrogen ions (H+).
The presence of H+ ions is what makes a solution acidic.
When alkalis are added to water, they form negative hydroxide ions (OH–).
The presence of the OH– ions is what makes the aqueous solution an alkali.

You have the concentration and volume.
Rearrange concentration=mol/volume and you'll get your answer.

Think about the number of H+ and OH- that dissociates in each compound
