Answer:
Molarity = 0.79 M
Explanation:
Given data:
Mass of KNO₂ = 67 g
Volume of solution = 1 L
Molarity of solution = ?
Solution:
First of all we will calculate the number of moles.
<em>Number of moles = mass/ molar mass</em>
Number of moles = 67 g / 85.10379 g/mol
Number of moles = 0.79 mol
Molarity:
Molarity = number of moles / volume in L
Molarity = 0.79 mol/1 L
Molarity = 0.79 M

<span>The balanced reaction that describes the reaction between hydrogen and nitrogen to produce ammonia is expressed 3H2 + N2 = 2NH3. The yield of the reaction is equal to the actual amount of product divided to the theoretical amount of product multiplied by 100 percent. 26.3 grams of H2 theoretically produces149 grams. The yield is 79 divided by 149 equal to 53.02 percent. </span>
