Because if they aren't properly included, it means that you are saying that the numbers can be anything, all reals.
Not including units is the same thing, if you don't properly lable the data table, you could be talking about anything.
Not giving a proper unit/variable is almost like giving someone permission to assume what you're talking about
Hello!
I'm going to have to infer that you meant "grams" and not "gallons" :-)
Anyways, to find the density, you need to the divide mass over volume (d = m/V).
Since we are given the volume being 15.0 mL, and the weight being 40.5 grams, we can find the density of the aluminum block.
40.5 grams / 15.0 mL = 2.7 g/mL
Therefore, the density of the aluminum block is 2.7 grams per milliliter.
They are identical to the nucleus of the helium-4 atom. So the answer is helium atoms.
Hope this helps! :)
The total pressure 1566 mm Hg.
Pressure is the force applied perpendicular to the floor of an object per unit location over which that pressure is shipped. Gauge strain additionally spelled gage pressure is the pressure relative to the ambient stress. pressure.
The SI unit of stress is pascal which is identical to one newton in keeping with rectangular meter. apparently, this name was given in 1971. earlier than that pressure in SI became measured in newtons in line with square meter.
Partial pressure of Argon = 429 mm Hg
Partial pressure of Neon = 1.2 atm
∵ 1 atm = 760 mm Hg
=> 1.2 atm = 1.2 * 760 mm Hg
= 912 mm Hg
Partial presser of He = 225 mm Hg
S0, Total pressure = Par + P ne + P he
= ( 429 + 912 + 225 ) mm Hg
= 1566 mm Hg
