Answer:
1.58 M
Explanation:
is 1.66 m concentration.
Which means that 1.66 moles of are present in 1 kg of the solvent, water.
Mass of water = 1 kg = 1000 g
Moles of = 1.66 moles
Molar mass of = 98.079 g/mol
The formula for the calculation of moles is shown below:
Thus,
Total mass = 1000 g + 162.81114 g = 1162.81114 g
Density = 1.104 g/mL
Volume of the solution = Mass / Density = 1162.81114 / 1.104 mL = 1053.27 mL = 1.05327 L
Considering:-
<u>Molarity = moles/ Volume of solution = 1.66 / 1.05327 M = 1.58 M </u>
1 moL of a substance is equal to 6.02 x 10^23 atoms or particles , it true statement. This number is known as Avogadro number.
