A piece of metal has 200 grams and a volume of 40 cm cubed.?

Question

What is it's specific gravity?

What is it's density?

Answer 1

Density = 200 / 40 g / cm ³
Density = 5 g / cm ³
Specific gravity = 5

Answer 2

Density = Mass / Volume = 200 / 40 = 5 gm/cc

Specific gravity = Density of the substance / Density of water

= 5 / 1 = 5

Answer 3

200 g for 40 cc means a density of 5 g/cc (or 5000 kg/m^3 to use proper SI units). The "specific gravity" is 5.

"Specific gravity" is the name given to the ratio of the density of a substance to the density of water (usually rounded to 1 g/cc, although the value 0.999972 g/cc is often used to establish printed tables, see links below for details). So the specific gravity of that metal is 5 (just the pure "dimensionless" number 5; DON'T specifiy a unit, a specific gravity is a pure number).

By the way, the proper abbreviation for "gram" is "g" NOT "gm", in spite of what you find all over the place, including in the (casual) work of reputable authors who should know better ("gm" is also erroneously built into at least one handheld scientific calculator, see last link below). Likewise, the correct abbreviation for the second of time is "s" NOT "sec".

Answer 4

density = mass /volume = 200 / 40 = 5 gm / cc
sp.gr = density of metal / density of water = 5 / 1 = 5
since density of water is 1 gm / cc . . . in cgs unit
