A solution of NaCl (MW = 58.5 g/mol) in water (MW = 18.0 g/mol) has the molality of 3.01 molal and the density of 1.112 g/mL. Consider mass of solvent 1 Kg A) What is the mass percent of the solute? (B) What is the molarity of the solution? (C)What is the mole fraction of H2O?
I need the density (g/mL) for the water column and the isopropyl
alcohol column. With math shown and included please! The question
requires me to show work. If possible, I would also like the
percent error's (with work shown) of the water and isopropyl
alcohol columns. Thank you!
Part 1: Volume and Density Measurements (Liquid) 1 Gather the graduated cylinder, distilled water, short stem pipet, and isopropyl alcohol. 2 Place the clean, dry, 25 ml graduated cylinder on the tared...
Isopropyl alcohol is mixed with water to produce a 38.0% (v/v) alcohol solution. How many milliliters of each component are present in 875 mL of this solution? Assume that volumes are additive. alcohol: mL water: ml The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. How many grams of sucrose are needed to make 695 mL of a 38.0% (w/v)...
