Answer:
7.97 moles of neon are present in the canister.
Explanation:
Avogadro's constant or "Avogadro's number" is the number of constituent particles found in the amount of substance in one mole.
In other words, Avogadro's number is the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number applies to any substance.
So, you can apply the following rule of three: if 6.023*10²³ atoms are present in 1 mole, 4.8*10²⁴ atoms are present in how many moles?
amount of moles= 7.97 moles
<u><em>7.97 moles of neon are present in the canister.</em></u>
Following reaction shows the preparation of
Nitrile from
Amide. In this reaction
Thionyl Chloride (SOCl₂)is reacted with Amide, which produced nitrile along with
SO₂ and
HCl gas. The
importance of this reaction is the removal of byproducts (i.e SO₂ and HCl). As both SO₂ and HCl are
gases so no extra workup is required to remove them. The
mechanism of reaction is as follow,
Answer:
1 grams Carbon Dioxide = 0.022722366761722 mole using the molecular weight calculator and the molar mass of CO2.
Explanation:
its a starter
- Glucose = C₆H₁₂O₆.
- Atomic mass of C = 12 u
- Atomic mass of H = 1 u
- Atomic mass of O = 16 u
- Therefore, the molecular mass of glucose
- = (6 × Atomic mass of C) + (12 × Atomic mass of H) + (6 × Atomic mass of O)
- = (6 × 12) + (12 × 1) + (6 × 16) u
- = 72 + 12 + 96 u
- = 180 u

Answer is: <span>C.)It will be closer to the mass of Vi–193.
</span><span>Average atomic mass of vitellium =
Ar(Vi-188) </span>· ω(Vi-188) + Ar(Vi-191) · ω(Vi-191) + Ar(Vu-193) · ω(Vi-193).
Average atomic mass of vitellium =
187.9122 amu · 0,10861 + 190.9047 amu · 0,12428 + 192.8938 amu · 0,76711.
Average atomic mass of vitellium = 20,409 + 23,725 + 147,970.
Average atomic mass of vitellium = 192,104.
