Answer:
Molarityof the solution is 0.1375 M.
Explanation:
We will first find the number of moles of diethyl ether (C4H10O) by finding its molar mass and measured mass.
Molar mass of diethyl ether (C4H10O) = 74.12 g.
Now, volume of diethyl ether (C4H10O) = 1.15 mL and its density = 0.7134 g/mL.
Therefore, measured mass of diethyl ether (C4H10O) = volume x density = 1.15 mL x 0.7134 g/mL = 0.82 g.
Now, number of moles of diethyl ether (C4H10O) =
= 0.011 Moles.
Volume of the solution = volume of diethyl ether + volume of dichloromethane = 1.15 mL + 78.85 mL = 80 mL.
Now, molarity of the solution = Number of moles of diethyl ether / Volume of the solution( in mL) x 1000 =
