Answer:
No. of molecules= mass/molar mass ×avogadro no.
= 13.2/50×6.02×10°23
No. of molecules =1.59×10°23
Explanation:
Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. ... The closeness, arrangement and motion of the particles in a substance change when it changes state.
Hi Again!
this question is another one for the PV=nRT formula
P is pressure, V is volume, n is moles, R is 8.314 and T is temperature
first this is turn your temperature in Kelvin, by adding 273 and you should get 308
Now you can plug into the formula
if you're solving for P, that means you are doing nRT divided by V
so you would sub in 8 for "n", 8.314 for "R", 308 for "T" and 12.0 for "V"
you would now end up getting P= 8.00×8.314×308 and then all of that divided by 12 L
and you should get 1707.141333 but with significant digits is turns into 1.70 ×10^1
and since you're finding pressure, your units are KpA
I think it’s a baller for you and your
In the United States, weather most often moves west to east, because that is the direction the jet stream blows. The jet stream carries weather systems along with it.
