Answer:
yes
Explanation:
oak trees don't have vertebrates
The number of molecules : 4.967 x 10²⁴
<h3>Further explanation
</h3>
A mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
8.25 moles of C₈H₁₈
The number of molecules :

Answer:
0.5832 miles =3079ft and 3.552 inches
Explanation:
This is if you are wanting the foot amount and the extra in inches, if you are wanting it in just feet and just inches it would be 3079.296 feet and 36951.552 inches
<span>570 torr.
The ideal gas law is
PV = nRT
where
P = pressure
V = volume
n = number of moles of gas particles
R = Ideal gas constant
T = absolute temperature
Since the value n, R, and T remain constant for this problem, that indicates that if the volume is doubled, the pressure will be halved. So the new pressure will be 1.50 atm / 2 = 0.750 atm. Now we just need to convert that from atm to torr. 1 atm is equal to 760 torr, so 0.750 atm * 760 torr/atm = 570 torr.</span>
Answer:
CS₂
Explanation:
To find the empirical formula we need to determine first the percentage of each atom in the molecule. Then, we need to find the moles and, as empirical formula is the simplest whole-number ratio of atoms we can solve the empirical formula:
<em>%C:</em>
0.33gC / 2.12g * 100 = 15.6%
<em>%S:</em>
1.53g S / 1.82g * 100 = 84.1%
In a basis of 100, the moles of each atom are:
<em>C:</em>
15.6g C * (1mol / 12.01g) = 1.30 moles
<em>S:</em>
84.1g S * (1mol / 32.065g) = 2.62 moles
The ratio of Sulphur-Carbon is:
2.62mol / 1.30mol = 2
That means empirical formula is:
