Answer:
Explanation:
The original calculation to find the number of moles which is 
can be rearranged to give the equation 
. Therefore the amount of molecules can be found by 
(multiplying by Avogadro's Number)
Answer:
Mass 1=3M
Mass 2=?
Volume1=75mL
Volume2=250mL
By using molarity formula:
<u>mass1*volume 1=mass2*volume 2</u>
3M*75=mass2*250
mass2=225/250
mass2:0.9M
<h3>the molarity of a solution is 0.9M.</h3>
Selective breeding
The Alleles
DNA
X and Y chromosome from mother and father
Nucleus
Gene
<u>Explanation:</u>
- In selective breeding, a specific trait of the animal is considered and the gene coding for that trait is used to create new breeds. Example - cow producing lot of milk.
- Genotypes are always expressed by the alleles.
- Example - Genotype of Tall plants would be TT or Tt
- Information is passed from parents to offsprings from the information stored in DNA.
- A gender of an individual is determined by the x chromosomes of mother and X and Y chromosome of father.
- X chromosome from mother and X chromosome from father would form a female and X chromosome from mother and Y chromosome from father would form a male.
- DNA is located inside the nucleus of the cell
- Gene is the segment of chromosome that codes for a specific protein. The non coding segment of chromososme is heterochromatin.
Answer:
a. 
b. 
Explanation:
Hello,
a. In this case, we use the Boyle's law as en inversely proportional relationship between pressure and volume:
Thus, for the given conditions, one computes the new pressure as shown below:
b. Now, we should find the final volume for a new pressure of 10 atm:
Best regards.
Answer:1 grams Magnesium Hydroxide is equal to 0.017146870490373 mole.
Explanation:The molecular formula for Magnesium Hydroxide is Mg(OH)2. The SI base unit for amount of substance is the mole.
