How many moles is 1.81 x 10^24 atoms of carbon?

Well a number you have to know is 6.02 x 10^23. That is how many atoms there are in a mole.

So if you have 1.81 x 10^24 atoms,
you divide that by 6.02 x 10^24 moles to get 3 moles

Using factor/label method:
1.81 x 10^24 atoms * 1 mol
                                   ------------------------   = 3 moles
                                   6.23 x 10^23 atoms
(As you can see, the unit "atoms" cancels out from the top and bottom.)

Answer:

Answer of question a is 345J.

Explanation:

In question a following is given in data:

-mass of iron (m) = 10.0 g

-temperature (ΔT) = final temperature- initial temperature= 100-25=  75 degree Celsius

-Specific Heat capacity of iron (c)= 0.46J/g°C.

Heat (Q)=?

Solution:

Formula for Heat is :

Q=m x c x ΔT

Q= 10 x 0.46 x 75

Q= 345 J.  

so, 345 joules of heat is needed to increase the temperature of 10 grams of iron.

  • From the above formula all other questions can easily be solved from the same procedure.

What is the definition of DNA in meiosis
mario62 [17]
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell. Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
