Question

use the following balanced equation to answer the questions: 2koh → k₂o + h₂o. there is 1 mole of h₂o present. the molar mass of water is 18.02 g/mol. what mass of water is present?

Explanation:

Step1: Recall mass - mole relationship

The formula to calculate mass ($m$) from moles ($n$) and molar mass ($M$) is $m = n\times M$.

Step2: Substitute given values

We know $n = 1\ mol$ (moles of water) and $M=18.02\ g/mol$ (molar mass of water). So $m=1\ mol\times18.02\ g/mol$.

Answer:

$18.02\ g$
