How many pounds of wax equals 16 fl oz?
What kind of wax ? Different waxes have different densities.
Can a combined substance be separated physically?
A substance that is chemically combined cannot be separated physically.In some situations, you can and can't separate combined substances physically. For example, you can separate sand from rocks physically, but you cannot separate water and ice cream, even though the substances did not undergo a chemical change, because the water soaked into the ice cream.
20 kilos flour to litres?
There can be no conversion.A kilogram is a measure of mass. A litre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion. Flours from different grains have different densities.
Why dont equal masses of golf balls and ping pong balls contain the same number of balls?
Their densities are different.
What property does separation by density rely on to separate out parts of a solution?
Separation by density relies on the property that different substances have different densities, causing them to settle at different levels in a solution. With this property, substances of higher density will sink to the bottom while substances of lower density will float to the top, allowing for separation based on these differences.
How do you separate layers of different densities?
Gravity - using a centrifuge to speed things up. Note that if the substances are mixable then this fails.
How can the volume of two substances be the same but the mass be different?
They have different densities.
What is the meanig of decantation?
Decantation is a process used to separate liquids from solids by carefully pouring off the liquid, leaving the solid particles behind. It is commonly used in chemistry labs to separate mixtures of substances that have different densities.
How many ug in a liter?
That depends on the substance. Different substances have different densities (mass / volume).
How gram is equal to 1 spoon?
A spoon is a measure of volume. Different substances have different densities so that the same volume of two substances can have very different masses.
Can you convert 0.5 mg to ml?
Yes, if you know the density of the substance. Different substances have different densities, i.e., different amounts of mass per volume. mg is a measure of mass, ml is a measure of volume.Yes, if you know the density of the substance.

How can we calculate the total density by adding together the densities of different substances?
To calculate the total density of a mixture of substances, you can add together the densities of each individual substance and divide by the total number of substances. This will give you the average density of the mixture.
Will every solid with the same volume have the same density?
No. Solids made of different substances will normally have different densities.
How many teaspoons are in 42 g?
This can't be answered without naming the substance. Different substances have different densities.
You rapidly swirl a mixture of substances with different densitites in a centrifuge what will happen?
Substances with greater densities will be pulled to the bottom of the test rube.
What happens if milk and sea water is mixed?
They would separate out because they have different densities.
