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?

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

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.

Answer it was we, the the whole people, who formed the union. and we formed it, not to give the blessings of liberty, but to secure them: not to the half of ourselves and the half of our posterity, but to the whole people- women as well as men.
