Atomic weight is Ar of the atom (what you see on the periodic table)
atomic weight<span> is relative </span>atomic mass, so yeah same thing
Answer:
36
Explanation:
There are 6 Carbon atoms, 12 Hydrogen atoms, and 18 Oxygen atoms.
Answer:
The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA.
Explanation:
Answer:
V = 25.7 L
Explanation:
To find the volume of Argon (Ar), you need to use the Ideal Gas Law equation. This looks like:
PV = nRT
In this formula,
> P = pressure (atm)
> V = volume (L)
> n = number of moles
> R = constant (0.0821 L*atm/K*mol)
> T = temperature (K)
While there is a different constant that can be used if you want to keep the pressure in mmHg, there is a more common constant used when the pressure is in atm. So, to find the volume, you need to (1) convert mmHg to atm (by dividing by 760) and then (2) calculate the volume (using Ideal Gas Law).
<u>(Step 1)</u>
600 mm Hg 1 atm
------------------- x --------------------- = 0.789 atm
760 mm Hg
<u>(Step 2)</u>
PV = nRT
(0.789 atm) x V = (0.825 mole)(0.0821 L*atm/K*mol)(300 K)
(0.789 atm) x V = 20.32
V = 25.7 L
