Sucrose will be the most effective. Hence, option D is correct.

<h3>What is sucrose?</h3>

Sucrose is simply the chemical name for sugar, the simple carbohydrate we know and love that is produced naturally in all plants, including fruits, vegetables and even nuts.

When salt or sugar (a solute) is combined with water or ice (a solvent) and is evenly distributed, the freezing point is lowered.

(C_{12}H_{22}O_{11} → C_{12}H_{22}O_{11})

A block of metal has a mass of 0.0694 kg. It displaces 3.6 mL of water. What is it’s density in g/cm^3
Ivan

Answer:

19.28 g/cm^3 to the nearest hundredth.

Explanation:

The volume of water displaced = the volume of the metal.

density = mass / volume

0.0694 kg = 0.0694 * 1000

=  69.4 g.

Density = 69.4 / 3.6

= 19.28 g/cm^3.
