The formula you need is D=m/v, where D is the density, m the mass and v the volume.
1ml = 1cm3
so 12ml = 12cm3
D (in this case) = 4.05/12 = 0.3375 g/cm3
Density = Mass/Volume = 12.75/15 = 0.85 grams per ml
Density is mass per unit volume, so mathematically, it's D=M/V. If your mass is 4.5 grams and your volume is 5 ml, then density is 4.5/5=0.9 g/ml.
The density is 0,3375 g/cm3.
-- Take an object or a sample of a substance-- Measure its mass, and express the result in grams-- Measure its volume, and express the result in cubic centimeters-- Divide the mass by the volume. The result of the division is the density of the object or substance,expressed in "grams per cubic centimeter".
2 grams per centimeter cubed. The equation to find this is D=M/V, which means density equals mass over volume.
The volume would be 9 cubic centimeters. If you meant to ask the density, that would be 4 grams per cubic centimeter.
Yes the number of moles = the number of grams in a given sample / the molecular mass of the substance. Ex. to convert 50 grams of nitrogen to # of moles of nitrogen, you divide 50g by 14.01g (the molecular mass) and you have 3.57 mol Nitrogen
Definition of density: Density = mass / volume; solving for density: volume = mass / density. Density of silver is about 10.5 grams/cm3.
The density of a substance is often expressed in units of grams per milliliter. If a substance with a volume of 60 ml weighs 85 grams the density is found by dividing the weight (85g) by the volume (60ml). This substance has a density of 1.42g/ml
The density is 16/5 grams per some unknown unit of volume - not a particularly useful measure of anything!The density is 16/5 grams per some unknown unit of volume - not a particularly useful measure of anything!The density is 16/5 grams per some unknown unit of volume - not a particularly useful measure of anything!The density is 16/5 grams per some unknown unit of volume - not a particularly useful measure of anything!
The density is 169/13= 13 grams/ml.
The density is 21 g/mL
Density = mass/volume. Density(A) = 40.2/5.7 = 7.05 gcm-3 Density(B) = 42.0/6.3 = 6.67 gcm-3 So B is less dense.
Density is mass per volume. Density is the amount of substance there is in a given container/space (the volume). Its SI units: grams/Litre (g/L)
This question makes no sense.Grams are a measure of weight;whereas centimeters are a measure of length.weight and volume (which would be cubiccentimeters) are related by the density of the substance.So that if the density of the substance was known, then multiplying the density (in grams per cubic centimeter) by the volume (in cubic centimeters) of the substance would give the weight (in grams) of the substance.
A substance with a density of 1.5.For example Calcium.
The object has a density of 20 g/mL
Volume = mass / density = 554g / 3.1 gcm-3 ~= 178.7 cm3
Density is mass/volume.Density of the unknown substance = 47.5g/23.0mL = 2.07g/mLHint: Mass is always measured in grams of some sort; mg, g, kg, etc... Volume is measured in mL, L, m3, cm3, etc...
Quarts are a measure of volume, grams a measure of weight. This depends on the density of the substance.
