Question

This is easy, just read the last question. (Already Asked this question before)

How many grams of Sodium Hydroxide could be produced if 1.2L of 3.0 M Calcium Hydroxide are consumed?

Na2CO3 + Ca(OH)2 --> 2NaOH + CaCO3

Now I know how to do equations like this, just a bit confused on how to use my conversion factors.

Do I need to use the 3.0 Molarity in this equation or can I just use Molar Volume of a gas (22.4L/1 mole)?

Answer 1

You would have to use the molarity of calcium hydroxide to find the moles of calcium hydroxide. Once you have moles, just convert using mole:mole ratio and find the grams of sodium hydroxide.
