The molecular weight of KMnO4 is 158 g/mol. If you wanted to make 500 mL of a 0.1M stock solution of KMnO4, how much solid KMnO4 would you need to add before filling mL flask of water?

Answers

Solid KMnO₄ needed = 7.9 g

Further explanation

Given

MW KMnO₄ = 158 g/mol

500 mL(0.5 L) of a 0.1M stock solution of KMnO₄

Required

solid KMnO₄

Solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]

Input the value :

n = M x V

n = 0.1 M x 0.5 L

n = 0.05 mol

Mass KMnO₄ :

= mol x MW

= 0.05 x 158 g/mol

= 7.9 g

The solid KMnO₄ a person need to add before filling water flask will be:

"7.9 g".

Molecular weight

According to the question,

Molecular weight of KMnO₄ = 158 g/mol

Volume of solution = 500 mL or,

                                = 0.5 L

Molarity = 0.1 M

We know the relation,

Molarity, M = [tex]\frac{n}{V}[/tex]

or,

→ n = M × V

By substituting the values,

     = 0.1 × 0.5

     = 0.05 mol

hence,

The mass of KMnO₄ will be:

= mol × Molecular weight

= 0.05 × 158

= 7.9 g

Thus the response above is appropriate.

C3H3N + O2 ⇒ C + H2O + N2

Answers

Answer:

4C₃H₃N   +    3O₂    →   12C  +   6H₂O    +     2N₂

Explanation:

The given reaction equation is expressed as:

        C₃H₃N   +    O₂    →   C  +   H₂O    +     N₂

The problem here entails balancing of the chemical reaction.

 So;

assign letters a,b,c,d and e as coefficients that will balance the expression:

 

            aC₃H₃N   +    bO₂    →   cC  +   dH₂O    +     eN₂

Conserving C :  3a  = c

                   H :   3a  = 2d

                   N :    a = 2e

                   O:    2b  = d

let a  = 1, c  = 3, e  = [tex]\frac{1}{2}[/tex]  , d  = [tex]\frac{3}{2}[/tex]  , b  =  [tex]\frac{3}{4}[/tex]

    Multiply through by 4;

          a  = 4, b  = 3, c  = 12 , d  = 6 and e  = 2

                4C₃H₃N   +    3O₂    →   12C  +   6H₂O    +     2N₂

3. How many grams of oxygen are needed for the
complete combustion of 11 grams of propane, C3H8?
C3H8 + 5 O2 + 3 CO2 + 4 H2O

Answers

Answer:

Mass = 40 g

Explanation:

Given data:

Mass of oxygen needed = ?

Mass of propane = 11 g

Solution:

Chemical equation:

C₃H₈ +5O₂   →     3CO₂ + 4H₂O

Number of moles of propane:

Number of moles = mass/molar mass

Number of moles = 11 g/ 44.1 g/mol

Number of moles = 0.25 mol

now we will compare the moles of propane and oxygen.

              C₃H₈        :          O₂

                  1           :            5

                0.25      :            5/1×0.25 = 1.25 mol

Mass of oxygen needed:

Mass = number of moles × molar mass

Mass = 1.25 mol × 32 g/mol

Mass = 40 g

In an experiment, zinc chlorate decomposed according to the following chemical equation. Zn(ClO3)2 → ZnCl2 + O2 (Molar mass of Zn(ClO3)2 = 232.29 g/mol; ZnCl2 = 136.286 g/mol; O2 = 31.998 g/mol) If the mass of zinc chlorate was 150 grams, which of the following calculations can be used to determine the mass of oxygen gas formed?

Answers

The mass of oxygen gas : = 61.98 g

Further explanation

Given

Reaction

Zn(ClO3)2 → ZnCl2 + O2

The mass of zinc chlorate was 150 grams

Required

The mass of oxygen gas

Solution

Balanced equation :

Zn(ClO₃)₂ → ZnCl₂ + 3O₂

mol of Zn(ClO₃)₂ :

= mass : MW

= 150 : 232.29 g/mol

= 0.6457

From equation, mol ratio of Zn(ClO₃)₂ → ZnCl₂ : O₂ = 1 : 3, so mol O₂ :

= 3/1 x mol  Zn(ClO₃)₂

= 3/1 x 0.6457

= 1.937

Mass of  O₂ :

= mol x MW

= 1.93  x 31.998 g/mol

= 61.98 g

Or we can use equation :

= (150 x 3 x 31.998) : (232.29 x 1) grams

= 14399.1 : 232.29

= 61.98 g

The number of moles of Zn(ClO₃)₂ was calculated as 150 g / 232.29 g/mol, substitute that value into the equation along with the molar mass of O₂ (31.998 g/mol) to find the mass of oxygen gas formed.

Given:

The mass of oxygen  = 61.98 g

The mass of zinc chlorate = 150 grams

The balanced reaction is:

Zn(ClO₃)₂ → ZnCl₂ + 3O₂

Mol of Zn(ClO₃)₂ :

Mass: MW

150: 232.29 g/mol

0.6457

From equation, mol ratio of Zn(ClO₃)₂ → ZnCl₂ : O₂ = 1 : 3, so mol O₂ :

= 3/1 x mol  Zn(ClO₃)₂

= 3/1 x 0.6457

= 1.937

Mass of  O₂ :

Mol x MW

=1.93  x 31.998 g/mol

= 61.98 g

= (150 x 3 x 31.998) : (232.29 x 1) grams

= 14399.1: 232.29

= 61.98 g
