Answer 13

You will need to make 20 mL. How many grams of NaOH powder will we need?

This is rather easy. Molarity is expresses in moles/liters or mmoles/ml
A Solution which is 2M will contain 2moles/liter or 2mmoles/ml.
In order to make 20ml, you will need 2x20 mmoles
NaOH MW is 40grams/mol or 40mgrams/mmol

Mass = MW x moles

The weight you need to weigh out is: 40 x 2 x 20 = 1600 mg or 1.6 g

Answer 25

.1M NaOH soln means 1 mole of NaOH dissolved in 1 l of water or 0.1 mole of NaOH dissolved in 100ml of water and so on. so grams of NaOH required is 0.1mole=(mol.wt.of NaOH)*.1=4g this is for you Richard
and @meme106 sure ill help you

Answer 26

is it B?
