Calculate the concentration of solution containing :
a. 0.2 mole of sodium hydroxide, NaOH, dissolved in water and made up to 100 cm3.
b. 9.8 grams od sulfuric acid, HF, dissolved in water and made up to 500 cm3.

Respuesta :

Answer:

the answer for a is 2mol/dm3

Explanation:

n=0.2mol of NaOH

v=100cm3

[tex]v = \frac{100}{1000} \\ v = 0.1 {dm}^{3} \\ concentration = \frac{n}{v} \\ = \frac{0.2}{0.1} \\ = 2mol {dm}^{3} [/tex]
