You've been asked to make a solution of sodium hydroxide with a concentration of 1.5 molarity and a volunteer of 150ml. how many grams of sodium hydroxide do you need?

To calculate mass in g we first need moles of NaOH for this preparation. For this purpose we use the formula

Molarity = no.of moles / solution in liter

Here we have

Molarity= 1.5M

Solution = 150ml

Convert it into liter we get

150/1000 = 0.15L

Putting in

No.of moles = molarity x solution in liter

= 1.5 x 0.15 = 0.225mole of NaOH

Now we can use these moles to calculate mass in gram by formula

No.of moles = mass in gram/molar mass

Molar mass of NaOH is 39.997g/mol

Now use

Mass in gram= no.of mole x molar mass of NaOH

= 0.225 x 39.997

= 8.999g = 9g

So

9g of NaOH is required to make 150ml of 1.5M solution.

answer; /// i do believe that the correct answer is (c)nuclear bond

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
