Answer:
C. the boiling point of water
Explanation:
B is correct because boiling point only usually differs among the same substance when pressure changes. So say you take one solution onto a mountain top and another at sea level, the boiling point will not be the same, but here we assume they are in the same place so it won't.
A cannot be because the containers are all different shapes (and we aren't talking about like molecular shape of water from what I assume, we mean macroscopically, so that can't be).
B cannot be because we have 4 different temperatures.
D cannot be because we have 4 different temperatures, and therefore different amounts of steam will be released per minute as not all the waters have reached boiling.
We know that 1 mole of anything has a volume of 22.4 liters.
And 1 mole of N2 gas has a weight of 28 grams.
Comparing them , we get the answer as 5.31
Answer:
D. 18.7 grams
Explanation:
The coefficients are the key.
Create a proportion with them, and the molar mass, and then solve for x:
Answer:
volume = 13097674418.528dm³
Explanation:
n = (3.52)*10^32/(6.02)*10^23)
n = (584717607.97)
n = volume /molar volume
molar volume at stp = 22.4dm³
volume= 584717607.97 x 22.4
volume = 13097674418.528dm³
