Hello!
How many molecules are in 30 liters of methane (CH4) at STP ?
We have the following information:
Knowing that by Avogadro's Law for each mole of substance we have 6.02 * 10²³ molecules, it is known that in STP (Standard Temperature and Pressure) one mole of any gas equals 22.4 L, then:
22.4 L ----------------- 6.02*10²³ molecules
30 L -------------------- y molecules
multiply the means by the extremes
Answer:
8.0625*10²³ molecules of methane

The dimensions of field are . The area can be calculated as follows:
Converting ,
1 km =1000 m
Thus,
or,
Since, cost of new artificial turf is , thus, cost for will be:
Therefore, cost of artificial turf for field will be .
Answer:
The answer is 6,158.46
Explanation:
I don't really get what you mean, but I'm guessing you want the answer to it.
Answer:
Yes is possible
Explanation:
MnSO4*7H2O(s) → MnSO4(s) + 7H2O(g)
This should be an endothermic reaction. The water molecules are interacting with the Mn2+ and SO42- ions within the crystal lattice of the compound. You must overcome those interactions, and so that would require the input of energy.
