How do I make 95% v/v ethanol that has a density of 0.7893 g/mL?
There is no use of the density as ethanol is liquid and hence we can directly measure the volume required. But if the solute is solid then we will calculate how much grams of the solid is required using the density formula i.e. density = mass/volume. Using this we will get mass = density × volume.
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?
How much do 3.15 mL of ethanol weigh? Consider that the density of ethanol is 0.789 g / mL
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)
190 proof ethanol is (assume) 95% by weight ethanol. The other 5% is water. The density of the solution is 0.816 g/mL. Calculate the molarity and molality of ethanol in the solution, (ethanol is C_2H_6O).
From a 95% ethanol (ETOH) stock solution, you need to make 250 mL of 70% ETOH. How much stock and how much RO water do you need to make this solution- Show your work.
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.
In a synthesis experiment 3mL of 25% (v/v) en in ethanol was used to make a complex Nickel salt. Calculate the mols of en used in this synthesis. You may assume a density of ethanol of 0.789g/mL and a density for en of 0.899g/mL. Report your answer in units of mol.
The density of ethanol is 0.789 g/mL. What is the density in units of kg/m3?
Beer is typically 6% ethanol. The density of ethanol is 0.789 g/mL, and a US pint is 473.18 mL. In one pint of beer, what is the mass of ethanol? Assume the alcohol percentage is (volume of alcohol) per (volume of solution).
What is the molarity of a 12.1% (v/v) solution of ethanol (C2H5OH)? The density of ethanol is 0.785g/mL and the molar mass of ethanol is 46g/mol.
