Carboxylic acids and alcohols have higher boiling point
than other hydrocarbons due to their polarity and from the fact that they form
very strong intermolecular hydrogen bonding. This is due to the large
difference in their electronegativity that forms between the oxygen and the
hydrogen atom.
Living organisms contain relatively large amounts of oxygen, carbon, hydrogen, nitrogen, and sulfur (thesefive elements are known as the bulk elements), along with sodium, magnesium, potassium, calcium, chlorine, and phosphorus (these six elements are known as macrominerals).
Answer:
mL sugar sold needed = 2.2215 mL sugar
Explanation:
mass sugar = 7.57 g
∴ wt% = 5% = (g sugar/g sln)×100
⇒ 0.05 = g sugar/g sln
∴ g sln = 100 g
⇒ g sugar = 5 g
∴ δ sugar = 1.157 g/mL
⇒ mL sugar = (5 g)×(mL/1.157 g) = 4.322 mL
⇒ mL sugar needed = (7.57 g)/(1.157 g/mL) = 6.543 mL
mL of the sugar sold needed = 6.543 mL - 4.322 mL = 2.2215 mL sugar
