The density of ethanol is 0.789 g/mL. How many grams of ethanol should be mixed with 225 mL of
water to make a 4.5% (v/v) mixture?
4.5 = volume C2H5OH / 225 + volume C2H5OH x 100
volume C2H5OH = 10.6 mL
10.6 mL x 0.789 g/mL = 8.36 g

If 46.9 mL of ethanol (density = 0.789 g/mL) initially at 7.2°C is mixed with 45.4 mL of water (density = 1.0 g/mL) initially at 28.5°C in an insulated beaker, and assuming that no heat is lost, what is the final temperature of the mixture?
22.7 mL of ethanol (density =0.789 g/mL) initially at 8.4 ?C is mixed with 30.5 mL of water (density = 1.0 g/mL) initially at 23.8 ?C in an insulated beaker. Assuming that no heat is lost, what is the final temperature of the mixture?
If 45.0 mL of ethanol (density=0.789 g/mL) initially at 9.0 C is mixed with 45.0 mL of water (density=1.0 g/mL) initially at 28.6 C in an insulated beaker, and assuming that no heat is lost, what is the final temperature of the mixture? I tried many times in trying to get the answer, but I keep getting it wrong. I appreciate who answers this writes it step by step. Thank you.
If 55.0 mL of ethanol (density = 0.789 g/mL ) initially at 6.0 ∘ C is mixed with 55.0 mL of water (density = 1.0 g/mL ) initially at 28.6 ∘ C in an insulated beaker, what is the final temperature of the mixture, assuming that no heat is lost? ( C EtOH =2.42J/(g⋅ ∘ C). ) Express the temperature in degrees Celsius to three significant figures.
If the density of ethanol, C2H5OH, is 0.789 g/mL. How many milliliters of ethanol are needed to produce 15.0 g of CO2 according to the following chemical equation? C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 H2O(l)
PART A How many grams of ethanol, CH3CH2OH, should you dissolve in water to make 0.400 L of vodka (which is an aqueous solution that is 6.86 M ethanol)? Express your answer with the appropriate units. PART B Using the density of ethanol (0.789 g/mL), calculate the volume of ethanol you need to make 0.400 L of vodka. Express your answer with the appropriate units.
