The boiling points of two or three other pairs of liquids in which one liquid has a lower molecular mass than the other can be studied in order to see if the pattern is consistent.
The boiling point of a substance refers to the temperature at which its vapor pressure is equal to the atmospheric pressure. The boiling point of a substance has a lot to do with its molecular mass.
Generally, substances that has a higher molecular mass has a higher boiling point except other factors at at work. In order to confirm whether the pattern that you are noticing about molecular weights and boiling point is consistent, three other liquids with different molecular masses, one being higher than the other can be studied and their boiling points compared.

A sample of Ammonia gas at 650mmHg and 15 degree has a mass of 56.8g.calculate the volume occupied by the gas. Take N=14, H=1,R=8.3145jk.
Answer:
The first thing we have to do is change and state all the units so that we can use our ideal gas law equation ([tex]PV = nRT[/tex]).
650 mmHg is a pressure unit, we have to convert this to kiloPascals. We know that 760 mmHg gives us 101 kPa.
[tex]650 \ mmHg \ * \ \frac{101kPa}{760 mmHg} = 86 \ kPa[/tex]
P = 86kPa
T = 15°C + 273K = 288K
R (Gas constant) = 8.31 kj/mol
Molar mass of Ammonia ([tex]NH_{3}[/tex]) = (1 x 3) + (14) = 17g/mol
n (moles) = [tex]\frac{mass}{molar \ mass}[/tex] [tex]= \frac{56.8}{17} =[/tex] 3.34 mol
V = ?
Rearrange the equation to solve for Volume:
[tex]V = \frac{nRT}{P}[/tex]
Substitute the values inside:
V = [tex]\frac{(3.34)(8.31)(288)}{(86)} = 93 L (rounded)[/tex]
Therefore 93 L of volume is occupied by the ammonia gas.

what would happen if we lost our planets core on earth blew up, would we all die or will we lose gravity or suficate, pls help. :I
Answer: if we lost our core it would be an entire fallout like fallout 76 we would have no way to protect ourselves from the radiation of space except for a select few that actually own astronaut suits tho we would not turn into monsters, sadly :( I wanna be a ghoul

nomenclature of this compound
Answer:
Nomenclature is the process of naming chemical compounds with different names so that they can be easily identified as separate chemicals. Inorganic compounds are compounds that do not deal with the formation of carbohydrates, or simply all other compounds that do not fit into the description of an organic compound.
