Ever wonder why your eyes are a certain colour ?or why you look like your mom or dad?well your genetic material know as Deoxyribonucelic acid (DNA) is the hereditary material found in the nucleus of eukaryotic cells (animal and plant) and the cytoplasm of prokaryotic cells (bacteria) that determines the composition of the organism. DNA is found in the nucleus of every cell, and it is exactly the same in each cell. There is another type of genetic material found in cells and viruses known as ribonucleic acid (RNA).

The best answer to this question is DNA. DNA holds the genetic makeup of the body in each individual cell. RNA is part of DNA. The nucleus holds the DNA. Ribosomes turn RNA into protein. That is why the answer cannot be RNA, ribosomes, or the nucleus.

How many moles is 34.4 g of Oxygen gas (O2)?

jasenka [17]

Answer:

n = 1.075 moles

Explanation:

Given that,

Mass of oxygen = 34.4 gram

The molar mass of oxygen gas = 32 g/mol

We need to find the number of moles of oxygen. We know that,

No. of moles = given mass/molar mass

So,

$n=\dfrac{34.4\ g}{32\ g/mol}\\\\=1.075\ mol$

So, there are 1.075 moles in 34.4 g of Oxygen gas.

How many molecules are in 4.00 x 10^2mg of ibuprofen?

Serggg [28]

Start by converting mg to g. There is .001g in every miligram, so there is 0.4g in this sample.

Then find the molar mass of ibuprofen (C13H18O2) which is 206.3g/mol

Then divide grams by the molar mass to get moles of C13H18O2: (0.4g)/(206.3g/mol) = 1.94x10^-3mol C13H18O2

Then multiply moles by Avogadro's number to get molecules: (1.94x10^-3mol)/(6.02x10^23) = 1.17x10^21 molecules of ibuprofen (C13H18O2)
