From the ideal gas law
pv=nRT , n is therefore PV/RT
R is the
R is gas constant =62.364 torr/mol/k
P=500torr
V=4.00l
T=500+273=773k
n={(500 torr x 4.00l)/(62.364 x773k)}=0.041moles
the number of molecules=moles x avorgadro costant that is 6.022x10^23)
6.022 x 10^23) x0.041=2.469 x10^22molecules
Answer:
Sulfur has the same amount, like all the other elements in group 16, has six valence electrons.
Explanation:
Compounds with different boiling points - b.
Only because<span> fractional distillationworks by having a temperature gradient in the column therefore different length hydrocarbons condence at different rays of different temperatures.This works because longer chain hydrocarbons have higher boiling points. </span>
Answer:
363.3 degrees K to the nearest tenth.
Explanation:
Apply Charles' Law which states that the volume of a gas at constant pressure is directly proportional to the Kelvin temperature.
23.5 C = 273 + 23.5 = 296.5 degrees K.
40.81 / 296.5 = 50 / x where x is the required temperature.
x = 296.5 * 50 / 40.81
= 363.27 degrees.
