what is the mass of 0.25 mol of koh?\nmolar mass koh = 56.11 g/mol\n0.25 mol koh = ? g koh

Answer:

14.0275 g

Explanation:

Step1: Recall mass - mole formula

$m = n\times M$ where $m$ is mass, $n$ is amount in moles, and $M$ is molar mass.

Step2: Substitute given values

$n = 0.25\ mol$, $M=56.11\ g/mol$ $m=0.25\ mol\times56.11\ g/mol$

Step3: Calculate the mass

$m = 14.0275\ g$
