Answer:
0.19615 M
Explanation:
Calculation of the moles of as:-
Mass = 10.91 g
Molar mass of = 278.1 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the reaction shown below:-
1 mole of is produced when 1 mole of
undergoes reaction.
0.03923 mole of is produced when 0.03923 mole of
undergoes reaction.
Mole of = 0.03923 mole
Volume = 200.0 mL = 0.2 L ( 1 mL = 0.001 L )
Molarity is defined as the number of moles present in one liter of the solution. It is basically the ratio of the moles of the solute to the liters of the solution.
The expression for the molarity, according to its definition is shown below as:
So,
<u>0.19615 M is the molarity of the solution.</u>
