How to calculate percent error of a melting point range?
olya-2409 [2.1K]

Answer:

3.9%

Explanation:

Exact melting point = 123°C

Measured melting point = 128°C

% error; |measured - exact|/exact × 100

% error = |123 -128|/128 × 100

%error = 3.9%

Percentage error in temperature measurement = 3.9 %

For each example, identify if the food contains mostly saturated or unsaturated fatty acids.
dedylja [7]

Answer:

1. Vegetable oil, which is a liquid at room temperature, is used in making cake batter. <u>Unsaturated</u>

2. Chocolate, which is solid at room temperature, is derived from a seed. <u>Saturated</u>

3. Butter<u>,</u> which is a solid at room temperature, is often used in cooking. <u>Saturated</u>

4. The oil inside flaxseed oil pills is liquid at room temperature. <u>Unsaturated</u>

Explanation:

Saturated fats are those kinds of fat that do not have a double bond between their carbon atoms when represented structurally. At room temperature, they tend to assume the solid-state, and they are mostly obtained from animal sources. Unsaturated fats do have a minimum of one double bond between their carbon atoms and tend to assume the liquid phase. They are mostly obtained from plant sources.<em> </em>

1. Vegetable oil is obtained from a plant source and is, therefore, unsaturated fat.

2. Chocolate even though it comes from cocoa is solid at room temperature and is mostly comprised of saturated fat.

3. Butter a solid at room temperature is mostly made up of saturated fat and is sourced from animals.

4. Flaxseed oil obtained from a plant source is mostly unsaturated fat.
