How many moles of acid were present in 50 ml or 1.0M HCl?

How many moles of water were produced in this reaction?

moles = M x L = 0.050L x 1.0M

How do you find out how many moles of water were produced in this reaction?

You don't have a reaction; I couldn't answer that.

To calculate the number of moles of acid present in a solution, you need to use the equation:

moles = concentration x volume

In this case, the concentration is given as 1.0M (1.0 mole per liter) and the volume is given as 50 mL (0.050 liters). Let's use this information to calculate the moles of acid:

moles of acid = 1.0M x 0.050 L = 0.050 moles

Therefore, there are 0.050 moles of acid present in 50 mL of 1.0M HCl.

To calculate the number of moles of water produced in a chemical reaction, you need to know the balanced equation for the reaction. Without that information, it's not possible to determine the exact number of moles of water produced.

Could you please provide the balanced equation for the reaction you are referring to?
