Assuming the volume is in cubic cm and not cm(!),
Density = Mass/Volume = 56g/28cm3 = 2 grams per cm3
Density = (mass) / (volume) = 42/28 =1.5 gm/cm3
To answer this the volume is needed, expressed in millilitres or cubic centimetres.
45/15= 3 Where density is equal to mass over volume
The material density is needed to convert from a mass unit to a volume unit.
Brass is an alloy which has a density which ranges between 0.0084 and 0.0087 grams per mm^3 So the mass will range between 318 times the density range.
density = mass/volumeso in your question grams is mass & ounce is volume. to answer your question one needs to know the density of the liquid.
It all depends what the substance is. If it's 28 grams of air, the volume is large. If it's 28 grams of rock or lead, the volume is much smaller.
2.3 inches=0.05842metres total volume=28*10^6*0.05842 Volume=1.6357*10^6 cubic metres Mass=1.6357*10^9 kg.Something wrong with data.In the sum density of water is 103kg per cubic metre.It is impossible.So I took it as 1000.If 103 should be applied multiply volume by 103 to get the mass.
The information is incomplete , the density is a ratio of mass and volume there fore needs a unit like grams/cubic cm or grams /cubic m etc. The SI derived unit of density is kgm-3, kilogram per cubic metre, because both a gram and a litre are one thousandths of their base unit it can also be expressed as gl-1, grams per litre. so please correct the info Assuming, Density = 1.4g per llitre Mass = Volume * Density = 20 *1.4 = 28 gl-1 (Gms would be gigametre seconds)
This cannot be sensibly answered. Milliliters is a measure of volume and the other is a measure of weight or mass.
1000/280 = 100/28 = 25/7 = 3.5714 grams per cubic centimeter
The Sun has about 333,000 times the mass of the Earth, while it has over 1,300,000 times the volume. The average density of the Sun's matter is about a quarter of Earth's density (25.5 %). Earth = 6 x 10^24 kilograms, volume 1.1 trillion cubic kilometers (1.08 x 10^12) Sun = 2 x 10^30 kilograms, volume 1.4 quintillion cubic kilometers (1.41 x 10^18)
