yulyashka [42]

Answer:

0.256 L  

Explanation:

We should use the following formula:

concentration (1) × volume (1) =  concentration (2) × volume (2)

concentration (1) = 0.82 M NaOCl

volume (1) = ?

concentration (2) = 0.21 M NaOCl

volume (2) = 1 L

volume (1) = [concentration (2) × volume (2)] / concentration (1)

volume (1) = [0.21 / 1] / 0.82 = 0.256 L

Small quantities of oxygen can be prepared in the laboratory by heating potassium chlorate, KClO 3 ( s ) . The equation for the
Pavlova-9 [17]

Answer:

Mass of O_2 produced = 32 g

Explanation:

Calculation of the moles of KClO_3 as:-

Mass = 82.4 g

Molar mass of KClO_3 = 122.55 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{82.4\ g}{122.55\ g/mol}

Moles= 0.67237\ mol

From the reaction shown below:-

2KClO_3\rightarrow 2KCl+3O_2

2 moles of potassium chlorate on reaction forms 3 moles of oxygen gas

So,

0.67237 moles of potassium chlorate on reaction forms \frac{3}{2}\times  0.67237 moles of oxygen gas

Moles of oxygen gas = 1 mole

Molar mass of oxygen gas  = 32 g/mol

<u>Mass of O_2 produced = 32 g</u>
