is the balanced form of the chemical equation.
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products.
12 hydrogen, 35 oxygen, and 22 hydrogens are present on both sides of the reaction.

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 =
