Answer to Question #270921 in General Chemistry for Cah

Question

What is the molar concentration of aki’s disinfectant if she dissolved 5Tbsp. Of NaCIO (sodium hypochlorite)in 3.8 liters of H2o(water)

Answer 1

5 tablespoons = 73.9ml

73.9ml = 73.9 cm³ = 73.9 × 10^-3dm³

Since, 22.4 dm³ = 1 mole

$\therefore$ 73.9 × 10^-3 dm³ = 0.0033 moles

molar concentration = number of moles/volume

= 0.0033/3.8 = 0.0087M$.$
