Answer:
Concentrations:
1. 12 g salt in 3 L water = 0,4 g salt / 100 ml water
2. 12 g salt in 6 L water) = 0,2 g salt / 100 ml water
3. 30 g sugar in 5 L water) = 0,6 g sudar / 100 ml water
Explanation:
The given data are expressions to deal with the concentration of solutions (a kind of homogeneous mixtures).
There are many forms or units to express the concentrations of the mixtures.
The three cases show mass of solute (salt or sugar) in volume of solvent (water).
One form to express the concentration of the solutions is as mass of solute per 100 mililiters of solvent, which is useful to compare with solutibility tables.
You can do that using the formula:
- (mass of solute in grams / volume of solvent in mililiters) × 100.
To find the concentrations of the given solutions, first you need to convert the volume of the solvent to mililiters (ml):
- 3 L water × 1,000 ml / L = 3,000 ml water
- 6 L water × 1,000 ml / L = 6,000 ml water
- 5 L water × 1,000 ml / L = 5,000 ml water
Concentrations:
1. (12 g salt / 3,000 ml water) × 100 = 0,4 g salt / 100 ml water
2. (12 g salt / 6,000 ml water) × 100 = 0,2 g salt / 100 ml water
3. (30 g sugar / 5,000 ml water) × 100 = 0,6 g sugar / 100 ml water
The father of a child with just one x chromosome has a nondisjunction event that results in a child with Turner syndrome who is colorblind.
A human chromosome is what?
Long DNA sequences are carried by chromosomes, structures that are found in the cell nucleus. The substance that contains genes is called DNA. It serves as the foundation for the human. Additionally, the proper DNA structure is aided by the proteins contained in chromosomes.
What do the chromosomes of the gender do?
When you are born, your X and Y chromosomal determine whether you are a boy or a girl. Gender chromosomes, as they are known, are actually called X and Y chromosomes in females. Men possess simply a X and a Y.

Some cells are more active than others and also more available-to-promise (ATP). Muscles, especially the cardiac muscle cells work continuously, so they have a large number of mitochondria since the need more energy.
Answer: Visual aids are very useful during presentations, as they can help convey a message in a way that is clearer and more relatable than words.One visual aid that is particularly useful is a graph. Graphs can be used to represent statistics. In this case, you can provide data on the type or the amount of technology of a classroom, and you can display this data on a graph.Another useful aid is photographs. You can show pictures of students using technology in the classroom. This can also serve a rhetorical purpose, by forcing the audience to connect positive images with the idea of technology in the classroom.
