Question

What weight of barium hydroxide is present inin 35 ml of 0.200 eq.wt. Barium Hydroxide

Answer 1

The molar mass of $=Ba(OH)_2$

$Molarity=$ $Moles\over Liter$

$= 171.33g/ mol$

We need to turn $35 ml$ of $0.200moles Ba(OH)_2$ into its equivalent mass

This is done by multiplying;

$0.200\times 171.34\over35ml$ $= 0.979g BaOH$
