Remember the formula for molarity:

[tex]molarity = \frac{moles}{volume} [/tex]
Where the volume is in liters.

From here, it's a "plug and chug" type of question.

They give you the molarity: 0.45M
They give you the volume: 600mL
Remember that there are 1000mL in every liter, so the converted volume is 0.6L.

Plug in what you have:
[tex]0.45 = \frac{moles}{0.6} [/tex]
To find moles, you need to multiply 0.45 by 0.6, which gives you 0.270 moles.

With moles you can find grams by multiplying 0.270 moles by the molar mass of the compound.

Hope that helps!

The grams of moles will be "0.27 moles".

Given values are:

  • Molarity = 0.45 M
  • Volume = 600 mL or, 0.6 L

As we know the formula,

→ [tex]Molarity = \frac{Moles}{Volume}[/tex]

By substituting the values, we get

→         [tex]0.45 = \frac{Moles}{o.6}[/tex]          

By applying cross-multiplication, we get

→      [tex]Moles = 0.45\times 0.6[/tex]

                  [tex]=0.27[/tex]

Thus the above answer is right.
