the very bottom of the ocean and they are relevant by most of the animals feed off of the animals that come out of he vents
Molar mass CO₂ = 12 + 16 x 2 = 44.0 g/mol
1 mole ------------ 44.0 g
9 moles --------- ? ( mass CO₂)
mass CO₂ = 9 x 44.0 / 1
mass CO₂ = 396 / 1
= 396 g of CO₂
hope this helps!
Answer:
The flask covered with plastic wrap will contain more water that the flas left exposed.
Explanation:
Both flask will undergo evaporation of the water inside them into gas. The plastic wrapped flask will have the gaseous water condense back to water and return to the flask while the exposed flask will have the moisture evaporate into the air around it.
Data:
V (volume) = 500.0 mL = 0.5 L
T (temperature) = 15.00ºC
(converting in Kelvin) → TK = TC + 273 → TK = 15 + 273 = 288 K
P (pressure) = 736.0 mmHg
R (constant) = 62.363 (mmHg*L/mol*K)
m (mass) = 2.688 g
M (Molar Mass) = ? (g/mol)
Formula: General Gas Equation
![P*V = n*R*T \to \boxed{P*V = \frac{m}{M} *R*T}](https://tex.z-dn.net/?f=P%2AV%20%3D%20n%2AR%2AT%20%5Cto%20%5Cboxed%7BP%2AV%20%3D%20%20%5Cfrac%7Bm%7D%7BM%7D%20%2AR%2AT%7D)
Solving:
![P*V = \frac{m}{M} *R*T](https://tex.z-dn.net/?f=P%2AV%20%3D%20%5Cfrac%7Bm%7D%7BM%7D%20%2AR%2AT)
![736*0.5 = \frac{2.688}{M} *62.363*288](https://tex.z-dn.net/?f=736%2A0.5%20%3D%20%20%5Cfrac%7B2.688%7D%7BM%7D%20%2A62.363%2A288)
![368 = \frac{2.688}{M} *17960.544](https://tex.z-dn.net/?f=368%20%3D%20%5Cfrac%7B2.688%7D%7BM%7D%20%2A17960.544)
Product of extremes equals product of means:
![368*M = 2.688*17960.544](https://tex.z-dn.net/?f=368%2AM%20%3D%202.688%2A17960.544)
![368M = 48277.94227](https://tex.z-dn.net/?f=368M%20%3D%2048277.94227)
![M = \frac{48277.94227}{368}](https://tex.z-dn.net/?f=M%20%3D%20%20%5Cfrac%7B48277.94227%7D%7B368%7D%20)
![M = 131.1900605\to \boxed{\boxed{M \approx 131.2\:g/mol}}](https://tex.z-dn.net/?f=M%20%3D%20131.1900605%5Cto%20%5Cboxed%7B%5Cboxed%7BM%20%5Capprox%20131.2%5C%3Ag%2Fmol%7D%7D)
Therefore: <span>The gas found to have such a molar mass is
xenon gas</span>
