-A seed is larger than a spore.
-A seed is more advanced because it can sustain plant life.
-Found in different locations.
-Seeds can sprout mostly anywhere but spores requires a wet environment in order to germinate.
-Seeds are multicellular whereas spores are unicellular.
Answer:
0.585 mol
25.7 g
Explanation:
There is some info missing. I think this is the complete question.
<em>Carbon dioxide gas is collected at 27.0 °C in an evacuated flask with a measured volume of 30.0L. When all the gas has been collected, the pressure in the flask is measured to be 0.480atm.
</em>
<em>
Calculate the mass and number of moles of carbon dioxide gas that were collected. Be sure your answer has the correct number of significant digits.</em>

Step 1: Given data
T = 27.0°C + 273.15 = 300.2 K
V = 30.0 L
P = 0.480 atm
n = ?
m = ?
Step 2: Calculate moles of CO₂
We can calculate the moles of CO₂ using the ideal gas equation.
Step 3: Calculate mass of CO₂
We know that the molar mass is 44.01 g/mol. Then,
Each of the Isotopic mass * its Abundance Sum together divide by 100.
(179.946706*0.12 + 181.948206*26.5 + 182.9502245*14.3 + 183.9509326*30.64 + 185.954362*28.43 ) / 100
You get 183.84 (5s.f. ) or (183.8417786)

Answer: dry ice is a solid which makes it different from a gas
Explanation:
1) The question contains an unknown unit
The number 8908.8 has to be in units of mass: for example, kg or grams.
Here you indicated L.
I am going to work assuming that L is a mass unit. So you can see the way to solve the problem, but you have to verifiy the real unit of the statement and substitute with it.
With that in mind you can find the density of the liquid from:
density = mass / volume
2) Calculate the volume.
The volume of the liquid is the volume of the vessel, because it is filled.
The volume of the vessel is calculated from the formula of volume for a rectantular prism.
Volume of a rectangular prism = area of the base * height = side * side * height
=> Volume = 10 dm * 4 dm * 6 dm = 240 dm^3 = 240 liter
3) Calculate the density:
density = mass /volume = 8,908.8 L / 240 liter = 37.12 L / dm^3
Answer: 37.12 L / dm^3
