Answer:
solid
Explanation:
The correct answer is option 2. One way of expressing concentration is by expressing it by parts per million or ppm. It is calculated by dividing the grams of solute and the grams of the solution, and the result is multiplied by 1 000 000. Parts per million is equal to 1 milligram of solute per kilogram of solution.
B.) Shape
C.) Color
D.) Volume
A) 64.5%
B) 88.6%
C) 81.5%
D) 92.8%
Answer:
B) 88.6%
Explanation:
Percent yield equals actual yield divided by theoretical yield
actual yield is 31.0g
theoretical yield is 35g
percent yield was 88.57 which rounds up to 88.6%
b. nucleotide.
c. peptide.
d. monomer.
A 12.5-g marble display 5.0 mL of water. The density is 2.5 g/ ml.
Density is defined as a measurement of how tightly packed the mass is within a substance or object. The concept of density is crucial because it enables us to predict which compounds will float and which ones will sink in a liquid. As a rule, objects float as long as their density is lower than the liquid they are placed in.
The density of a substance is determined by the mass, size, and arrangement of its atoms. Density is calculated by dividing a substance's mass by its volume.
Density = Mass / Volume
Given Mass = 12.5 g
Volume = 5.0 ml.
Density = 12.5 g / 5.0 ml
Density = 2.5 g / ml
Thus, a 12.5-g marble display 5.0 mL of water. The density is 2.5 g/ ml.
