Verified answer

V=pi x r2 x h

V=348.71cm3

Mass of Argon gas is 188.87-188.25= 0.62 grams

density= grams/cm3

.62 grams/348.71 cm3=

.0017 g/cm3= Argon's Density

Sounds difficult but its really pretty simple:

Density= mass/volume

So in order to find the density you need to find the mass of argon and the volume.

Since the length (27.75) and the radius (2.00cm) has already been given, you can calculate the volume by simply substituting these numbers in the formula for the volume of a cylinder (V=pi*r^2*h):

V= 3.14*4*27.75= 348.54

finding the volume is the hardest part now to find the mass of argon simply subtract the mass of the empty tube from the mass of the tube filled with argon: 188.87-188.25= .62g argon

Now put both answers in the formula for density:

Density= mass/volume = .62/348.54 = .00178g/cm^3

Check calculations but the method is correct

exciting problem! Density is defined because of the fact the mass of a substance in keeping with unit volume. In different words, divide mass by potential of volume. in this problem cm3 potential cubic centimeter. a million cm3 is a unit of volume. For this problem, divide 234 g by potential of seven.9 cm3 to get 29.62 g/cm3. ask your self the place the rock got here from--it did no longer come from Earth. The densest nicely-known substance on earth at common situations of a million environment and 25°C is the ingredient osmium (Os). It has a density of twenty-two.fifty seven g/cm3.
