Question:

When 9.36 g sodium hydroxide is dissolved in enough water to make a total volume of 965 mL, what is the concentration of the resulting solution?

Answer:

Answer:

0.2425 M

Explanation:

Given mass = 9.36 g

Molar mass of NaOH = 39.997 g/mol

The formula for the calculation of moles is shown below:

?f=moles%20%3D%20%5Cfrac%7BMass%5C%20taken%7D%7BMolar%5C%20mass%7D

Thus,

?f=Moles%3D%20%5Cfrac%7B9.36%5C%20g%7D%7B39

?f=Moles%5C%20of%5C%20NaOH%3D%200

Given that:- Volume = 965 mL = 0.965 L ( 1 mL = 0.001 L )

So,

Considering:

?f=Molarity%3D%5Cfrac%7BMoles%5C%20of%5C%20solute%7D%7BVolume%5C%20of%5C%20the%5C%20solution%7D

?f=Molarity%3D%5Cfrac%7B0.234%5C%20mol%7D%7B0.965%5C%20L%7D%3D0
