Answer:
1) 72 mole
2)1152 mole
3)256 mole
4) 2890 mole
Explanation:
very important for u
number of mole= given mass/molecular mass
symbolically : n= m/Mm
1) first atomic mass (carbon =12)
n=6gram × 12gram /mole
n=72mole
2) atomic mass (Magnesium =24)
48 gram × 24 gram /mole
n= 1152 mole
3)atomic mass (oxygen = 16×2=32
n= 8 gram × 32 gram/ mole
n= 256mole
4) atomic mass ( Nitrogen =14 , hydrogen = 1×3
14+3=17
n= 170 gram × 17 gram / mole.
n= 2890 mole
Moles of Oxygen they took in : C. 2.42
<h3>Further explanation</h3>
The gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08205 l.atm / mol K
T = temperature, Kelvin
P=1000 kPa
V = 6 L
T = 298 K
moles of Oxygen :
Answer is: the author’s perspective on events.
The book Of Wolfes and Men was written in 1978 by Barry Holstun Lopez.
Barry Lopez (1945 -) is an American author, essayist and fiction writer.
On this page, the wolf is not noticing the seeds on his fur. Seeds fall off as the wolf moves along the trail, so only author can make this observation.
