PLEASE ANSWER ASAP!

Find the number of grams of hcl needed to react completely with .50 moles of magnesium.

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
