What is the molarity of a solution made by dissolving 8.56 g of sodium acetate in water and diluting to 750.0 mL?

Answer 1

0.139 M

The mole mass of sodium acetate is 82.0343 because 82.0343 gm of sodium acetate in 1000 ml of water is equal to 1 M molarity. Molarity is defined as gm mole solute dissolve per liter of solvent.

So,

Dissolved 8.56 grams in 750 milliliters of water

hence # 8.56/750*1000/82.0343=0.139#

Therefore, the solution's molarity is 0.139 M.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
