Question

Which equation shows how to calculate how many grams (g) of KCL would be produced from 4 mol KOH the balanced reaction is mgcl2 + 2koh -> mg(oh)2 + 2kcl?

Answer 1

first of all, we need tô calculate moles of KCl
next, mass=mol×molar mass

Answer 2

I think the correct answer from the choices listed above is option B. The equation that shows how to calculate how many grams (g) of KCL would be produced from 4 mol KOH would be

4 mol KOH ( 2 mol KCl / 2 mol KOH ) (74.55 g KOH / 1 mol KOH)

Hope this answers the question. Have a nice day.
