Molarity of aqueous solution is 1.9 M
The molarity in given case can be calculated by the formula -
M = number of moles/Volume of solution in liters
Number of moles is further calculated by the formula -
Number of moles = mass/molar mass
As we know, molar mass of ethanol is 46 g/mol
Keep the values in formula to calculate number of moles.
Number of moles =
Number of moles = 0.02
As we know, 1000 ml = 1l
So, 10.5 ml = 0.0105 l
Keep the values in formula of molarity to calculate the molarity -
Molarity =
Molarity = 1.9 M
Hence, the molarity of given aqueous solution is 1.9 M.
