A 0.2 M solution of NaCl contains ________ g of NaCl in 1 l of ________.

Maksim231197 [3]

Answer:

11.7 g in 1 L of water.

Explanation:

Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.

It is defined as mol/ L (number of moles per litre).

0,2 M means we have 0,2 mol/ L

In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol

$\frac{1 mol NaCl}{58.443 g}$ = $\frac{0.2 mol}{X g}$

X= $\frac{(0.2 mol x 58.433 g}{1 mol}$

X= 11.69 g

The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.

The hardy-weinberg principle states that _____ in a population do not change unless outside factors affect the gene pool.

Reika [66]

Answer;

-Allele frequencies

The hardy-weinberg principle states that allele frequencies in a population do not change unless outside factors affect the gene pool.

Explanation;

Hardy-Weinberg principle is a mathematical model that describes how genotype frequencies are established in sexually reproducing organisms.

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including mutations, natural selection, nonrandom mating, genetic drift, and gene flow.

The ABO blood group assorts independently of the Rhesus (Rh) blood group and the MN blood group. Three alleles, IA , IB , and i,

Eva8 [605]

Answer:

Part 1:

The mother’s genotype is ii, rr, MN

The father’s genotype is IAIA/IAi, Rr, MM

Part 2:

Approximately 1/32 (3.125%) of children can be expected to have the stated blood types.

Explanation:

Part 1:

The mother has blood types 0, Rh- and MN. Therefore, her genotype has to be ii, rr, MN.

The father has ABO type A. His ABO genotype may therefore be either IAIA or IAi, as both are compatible with type A offspring with a type 0 mother. His Rh genotype must be rr, since his Rh- child necessarily has to have inherited one r allele from each parent. Finally, his MN genotype has to be MM since both alleles are codominant.

Part 2:

Using the given data, we build the following Punnett chart:

IA R N IA r N i R N i r N

IA R M

IA R N

IA r M

IA r N

IB R M

IB R N

IB r M X

IB r N

Note that, of all 32 possible combinations, only a single one of them (marked with “X” produces a genotype which matches the desired blood type, as follows:

genotype: IBi, rr, MN

blood type: B, Rh-, MN

The steps of mitosis are shown. In Prophase, the cell starts to break down structures. In Metaphase, the chromosomes line up at

Ira Lisetskai [31]

Answer:

In Prophase of Mitosis cell division, the chromatin that is present in the nucleus starts condensation.

In Metaphase of mitosis, the chromosomes arrange itself at the equator or center of the cell.

In Anaphase, the daughter chromatids separate from each other and moves towards the poles. In Telophase of mitosis, the parent cell is divided into two daughter cells.

The difference in an area with high concentration and an area with low concentration is called:.

Musya8 [376]

The difference in an area with high concentration and an area with low concentration is called concentration gradient.

<h3>What is concentration gradient?</h3>

Concentration gradient refers to the difference between the concentrations of two solutes in a solution.

A solution usually contains an area or region with higher concentration and an area with lower concentration.

The difference between these two areas of different concentrations is referred to as a concentration gradient.
