How many grams of ethanol, CH3CH2OH, would you dissolve in water to make 2.75 L of vodka (which is an aqueous solution that is 6.86 M ethanol)? Using the density of ethanol (0.789 g/mL), calculate the volumes of ethanol and water you need to make 2.75 L of vodka. Please show all work. Thank you!
3. How many moles of HCl are there in 0.1 L of 0.1 M HCI? 4. In Lab 5, you will be using a compound ONPG which has a molecular mass of 300 grams/mol. If you dissolve 30 grams of ONPG in 1 liter of water, what is your final (ONPG] in molar (M)? What is the final concentration in mM? 5. How many grams of ONPG must you dissolve in 1 liter of water to get a solution that...

(h-58 m Calculate the mole fraction of NaCI in a solution that is prepared by dissolving 20.0 g NaCI in atm 11. 90.0 g of H20. 12. Calculate the parts per million of a solution made by dissolving 0.340 g of NH, in 2.00 x 10 mL of water (MMNH3-17.04 mol, di 20 = 1.00 mL).
How many moles of Na2S2O3 are needed to dissolve 0.354 mol of AgBr in a 1.0 L solution if Ksp for AgBr is 3.3×10−13 and Kf for the complex ion [Ag(S2O3)2]3− is 4.7×1013? The answer should include two significant figures.
The Henry's law constant (kH) for O2 in water at 20°C is 1.28e-3 mol/l atm. How many grams of O2will dissolve in 3.5 L of H2O that is in contact with pure O2 at 2.4 atm?
How many moles of Na2S2O3 are needed to dissolve 0.65 mol of AgBr in a solution volume of 1.0 L, if Ksp for AgBr is 3.3×10−13 and Kf for the complex ion [Ag(S2O3)3−2] is 4.7×1013? Remember to use correct significant figures in your answer (round your answer to the nearest tenth).

How many moles of calcium hydroxide dissolve to generate one mole of dissolved calcium? Given your answer to CTQ 10 and the concentration of calcium in the final solution calculate the mass of calcium hydroxide that can dissolve in 1 L of our 1.0 M solution of sodium hydroxide? (calcium hydroxide MW = 74.09 g/mol) Compare the solubility of calcium hydroxide you just calculated to the solubility of calcium hydroxide in pure water. By what factor did the “common ion”...
