Density is mass divided by volume. As you have given the mass and volume in valid SI units (ml - milliliter is equal to cubic centimeter) just divide 25 by 15 and get a density of: 0.60grams per cubic centimeter
(the extra, trailing 0 is because the original measurements had resolution of two significant figures and so the answer should also have two figures)
1.25 g/cm^3
Simply use d = m/v
Given m = 25g and v = 20 cm^3
1.25 g/cm3
Ethanol (USP grade) has a density of 0.810. From here we have to use the formula: d=m/v, where d is density, m, mass and v, volume. Solving for volume, we have v=m/d, therefore: v= 15/0.810 = 18.52 mL of ethanol are equivalent to 15g.
Density is the quotient of the mass and the volume. 15 grams ÷ 5.0 mL = 3.0 g/mL
1 mL = 1 cm3 Density = mass / volume Mass = 15 g Volume = 30 cm3 Density = .5 gcm-3 (grams per centimeter cubed)
density=mass/volume
Density of that object is 2.8
The formula for density is mass/volume, hence the density is 15/5=3g/cm3
You need to know the volume because the density is the ratio mass/volume.
Density = Mass/Volume = 30/15 = 2 grams per millilitre.
density = mass/volume density = 15/20 = 3/4 units/ml
Mass = 15 gm Volume = 2 cubic cm Density = Mass/Volume = 15/2 = 7 and 1/2 or 7.5 g per cm3
By definition: density = mass / volume Solving for volume: volume = mass / density Please note that a boy will NOT have a density of 15, at least, not if you use anything remotely related to SI units. The density of a person is close to that of water - with a density of 1, or 1000, depending on the units used.
Density = Mass/Volume = 30/15 = 2 grams per mL.
Density = mass/volume = 36/15 = 2.4 g per cm3
If you are given the volume [V] and density [p], the object`s mass [m] is given by the relation: m = p*V , where (*) indicates multiplication. Also, make sure that all units are in the same measurement system (Metric, Imperial, etc.) As an example, lets say I have a tank of water (p=1000 kg per m3 for water) that is 15m3 in volume. The mass of water in the tank is: m = (1000)*(15) kg = 15, 000 kg
Density = Mass/Volume = 15/60 = 0.25 grams per millilitre.
Density = Mass/Volume = 15/10 = 1.5 g per mL
The mass is volume x density; so it is necessary to know the density of this liquid.
