QUESTION 1 How many milliliters of an 80% (V/V) solution of isopropyl alcohol would you need to make 355 mL of a 47.1% (v/v) solution of isopropyl alchohol? QUESTION 2 The ratio of solute to solvent expressed in some set of units is the QUESTION 3 For very dilute solution we sometimes use parts per million, also known as QUESTION 4 How many grams of NaOH would be needed to make 773 mL of a 2.76 M solution?...
Isopropyl alcohol is mixed with water to produce a 31.0% (v/v) alcohol solution. How many milliliters of each component are present in 745 mL of this solution? Assume that volumes are additive. alcohol: mL water: mL
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)...

1) How many milliliters of 0.20M PMSF stock solution do you need to make 80 mL 1.2 mM PMSF solution? 2) What is the [H+] (in M) if the pH is 2? 3) What is the [OH-] (in M) if the pH is 12.5 (the digits before the decimal point in a logarithm are not significant figures)?
1. A solution of rubbing alcohol is 76.5 % (v/v) isopropanol in water. How many milliliters of isopropanol are in a 77.5 mL sample of the rubbing alcohol solution? Express your answer to three significant figures. 2. How many liters of a 3.18 M K2SO4 solution are needed to provide 98.8 g of K2SO4 (molar mass 174.01 g/mol)? Recall that M is equivalent to mol/L. Express your answer to three significant figures.
