Answer:
2.40 M
Explanation:
The molarity of a solution tells you how many moles of solute you get per liter of solution.
Notice that the problem provides you with the volume of the solution expressed in milliliters,
mL
. Right from the start, you should remember that you must convert this volume to liters by using the conversion factor
1 L
=
10
3
mL
Now, in order to get the number of moles of solute, you must use its molar mass. Now, molar masses are listed in grams per mol,
g mol
−
1
, which means that you're going to have to convert the mass of the sample from milligrams to grams
1 g
=
10
3
mg
Sodium chloride,
NaCl
, has a molar mass of
58.44 g mol
−
1
, which means that your sample will contain

molar mass
1 mole NaCl
58.44
g
=
0.004791 moles NaCl
This means that the molarity of the solution will be

The answer is rounded to three sig figs, the number of sig figs you have for the volume of the solution.
From: Yy Ss Hh 8 different gametes can be formed
- 5 Eye Color Genes = 243 genotypes
- 10 Eye Color Genes= 59049 genotypes
- 20 Eye Color Genes= 3,486,784,401 genotypes
This is further explained below.
<h3>What is a gamete?</h3>
Generally, Gametes are the cells of an organism that are responsible for reproduction. In certain contexts, they are also referred to as egg cells and sperm cells.
The popular word for female gametes is ova, whereas the common name for male gametes is sperm. Ovum and egg cells are other frequent names for female gametes.
Gametes are instances of haploid cells since they only contain a single copy of each chromosome. Haploid cells are described as having only one copy of each chromosome.
In conclusion, For 5 Eye Color Genes
3^n is implored hence
3^5=243 genotypes
Repeating said pattern e have
- 10 Eye Color Genes= 59049 genotypes
- 20 Eye Color Genes= 3,486,784,401 genotypes

4. Consider the following genotype: Yy Ss Hh. We have now added the gene for height: Tall (H) or Short (h).
a. How many different gamete combinations can be produced?
b. Many traits (phenotypes), like eye color, are controlled by multiple genes. If eye color were controlled by the number of genes indicated below, how many possible genotype combinations would there be in the following scenarios?
a. 5 Eye Color Genes:
b. 10 Eye Color Genes:
c. 20 Eye Color Genes:
Matter is every object that stands on this Earth
Answer:
1 = one
2 = fluorine
3 = Bromine
4 = increase
5 = first increaseas and then decreases

The hydrogen bonds that form between water molecules account for some of the essential and unique properties of water. The attraction created by hydrogen bonds keepswater liquid over a wider range of temperature than is found for any other molecule its size.
Hope this helped!
