Question

The mass of nickel(II) hydroxide that is dissolved in 250 mL of a saturated solution is ____grams.

Answer 1

Answer #1

Molarity of saturated solution of Ni(OH)4=0.13g/lit

i.e 0.13g dissolved in 1000ml of solution.

1000ml have 0.13g of Ni(OH)2

1ml have 0.13g/1000 of Ni(OH)2=0.00013g

250ml have 0.00013*250=0.0325g of Ni(OH)2

Answer 2
