<span>N2, penta means 5, so 5 oxygens
so with that being said n205</span>
Answer:
201.9
Explanation:
when you divided 760 with 400 yo get 19.0 the add it with 200 you get that answer
3.74×![10^{21}](https://tex.z-dn.net/?f=10%5E%7B21%7D)
3.74 ×
molecules of propane were in the erlenmeyer flask.
number of moles of propane can be calculated as moles of propane.
mass of propane = 0.274 g
molar mass of propane = 44.1
So this gives us the value of 6.21×
moles of propane
No one mole of propane As a 6.0-2 × ![10^{23}](https://tex.z-dn.net/?f=10%5E%7B23%7D)
so, 6.21 ×
× 6. 022 × 10^23
= 3.74 ×![10^{21}](https://tex.z-dn.net/?f=10%5E%7B21%7D)
Therefore, molecules of propane were in the erlenmeyer flask is found to be 3.74 ×![10^{21}](https://tex.z-dn.net/?f=10%5E%7B21%7D)
<h3>What is erlenmeyer flask?</h3>
- A laboratory flask with a flat bottom, a conical body, and a cylindrical neck is known as an Erlenmeyer flask, sometimes known as a conical flask or a titration flask.
- It bears the name Emil Erlenmeyer after the German chemist.
<h3>What purpose does an Erlenmeyer flask serve?</h3>
- Liquids are contained in Erlenmeyer flasks, which are also used for mixing, heating, chilling, incubating, filtering, storing, and other liquid-handling procedures.
- For titrations and boiling liquids, their sloped sides and small necks make it possible to whirl the contents without worrying about spills.

Answer:
The genetic code is stored in the DNA. DNA is a molecule formed by a sugar, deoxyribose, a phosphate group and four combined nitrogen bases: Adenine (A), Thymine (T), Cytosine (C) and Guanine (G). A gene is a part of DNA.
Answer:
47.8 g
Explanation:
Remember the equation for percent yield:
% yield = actual / theoretical
We're given two of the values in the question, so plug n' play:
0.945 = 45.2 / theoretical
theoretical = 47.8 g
Keep in mind you can use mass here without converting to moles because we're working with products only. If you were given a mass of reactants, you would need to convert to moles and using a balanced chemical equation find the corresponding moles of product produced.
