If there is sufficient water in the reaction system, how many grams of KOH can be produced from 22.2 g of K?

31.9 g of KOH can be produced from 22.2 g of KOH

Explanation:

To calculate the moles :

According to stoichiometry :

2 moles of produce = 2 moles of

Thus 0.57 moles of will produce=  of

Mass of

Thus 31.9 g of KOH can be produced from 22.2 g of KOH

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
