how many moles of C6H12O6 is needed to produce 3,5 L of a 5% (w/v) solution?...
Commercially available aqueous solutions of glucose (C6H12O6) are typically labeled as having a concentration of 5%(w/v). This means that a 100 mL sample of the solution contains 5 g of C6H12O6. a. How many moles of glucose are in a 4.16 mL sample of a 5%(w/v) solution? Hint: first calculate the mass of glucose in the 4.16 mL sample given that a 100 mL sample contains 5 g of glucose; then convert mass to grams. NG 2 b. If you...

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)...
