Which solution contains the smallest number of moles of sucrose (c12h22o11, molar mass = 342.30 g/mol)? 2,000 ml of a 5.0 × 10–5

Iteru [2.4K]

> 2,000 mL of a 5.0 × 10–5% (w/v) sucrose solution

5.0 × 10–3 g/mL * 2000 mL * (1 mol / 342.30 g) = 0.0292 mol

> 2,000 mL of a 5.0 ppm sucrose solution

5 grams / 1000000 mL * 2000 mL* (1 mol / 342.30 g) = 0.0000292 mol

> 20 mL of a 5.0 M sucrose solution

5.0 M * 0.020 L = 0.1 mol

Answer:

2,000 mL of a 5.0 ppm sucrose solution

What two molecules were condensed in an aldol condensation to produce (ch3)3cch=chcoch3?

inessss [21]

The given compound is being synthesized by condensing Acetone and Pivaldehyde (Trimethylacetaldehyde).

First Acetone is treated with Base, the base abstracts the mildly acidic proton present at alpha position to carbonyl group. The resulting specie called enolate act as a nucleophile and attacks on highly reactive aldehyde which upon dehydration yields the Aldol Product. The Reaction is as follow,
