Question

How many moles are in 5.96 g KOH ?

Answer 1

\[Moles = \frac{Grams}{MolecularMass}\]

where Molecular mass is in units of g/mol

Answer 2

Heres a molar mass calculator ,should sort you out http://www.webqc.org/mmcalc.php

Answer 3

The molecular mass of
K = 39.0g/mol
and
O = 15.9994g/mol
H = 1.00794g/mol
Note these are all listed on the periodic table

Take the sum of these

1.00794g/mol+15.9994g/mol+39.0g/mol

and insert them into the equation along with the weight of KOH you have

Answer 4

Really you shouldn't use that molecular mass calculator until you are comfortable with determining molecular mass of compounds, it is really easy to do

Answer 5

Agreed
