Answer:

It acts as a filter to prevent as much germs, or chemicals/substances, as possible from entering your immune system through your breathing. This is whether you're in a lab or in a grocery store with a pandemic going around. Not only does it protect you but it also protects those around you by filtering any germs you may already have in your system and preventing them from passing on to another person. That is why you should always wear your mask over your mouth <em>and</em> your nose.

A compound is found to contain 38.65 % carbon, 16.25 % hydrogen, and 45.09 % nitrogen by mass. what is the empirical formula for

iren [92.7K]

The molar mass of carbon is 12, hydrogen is 1, and nitrogen is 14, hence the ratio are:

C = 38.65 / 12 = 3.22

H = 16.25 / 1 = 16.25

N = 45.09 / 14 = 3.22

Divide the three by the lowest ratio which is 3.22:

C = 3.22 / 3.22 = 1

H = 16.25 / 3.22 = 5

N = 3.22 / 3.22 = 1

So the empirical formula is:

CHN
