An empty weighing dish has a mass of 1.0041 ± 0.0002 g. After you add dried sodium chloride to the dish, the mass is 3.2933 ± 0.
Maurinko [17]

Answer:

The correct answer to the following question will be "0.0013%".

Explanation:

The given values are:

Weight of an empty dish = 1.0041 ± 0.0002 g

Weight of dish + sodium chloride (NaCl) = 3.2933 ± 0.0002 g

Weight of NaCl = 2.2892 ± 0.0002 g

Now,

Volume of the solution = 500.00 ± 0.05 ± 0.0002

                                      = 500.00 ± 0.0502 ml

So,

Molarity = \frac{W \ NaCl}{M \ NaCl} \times \frac{1000}{Volumes \ of \ solution}

On putting the values in the above formula, we get

             = \frac{(2.2892\addeq +0.0002)}{58.440}\times \frac{1050}{(500.00+0.0502)}

             = (3.917 ± 0.0002) × (2 ± 0.0502)

             = (0.7834 ± .00001004)

Now,

Absolute error = \frac{0.00001004}{0.7834}\times 100

                         = 0.0013%
