Mass by difference?
mass by difference is an indirect way to find the mass of an object. For example, if you know the mass of a 'beaker and the substance in it' and the 'mass of the beaker', you can determine the mass of the substance by subtracting (mass of beaker + substance) - (mass of beaker)
When you divide the mass of a substance by its volume you get its what?
When we divide the mass of a substance by its volume we get its density.
When a substance changes from a solid to a liquid its density normally decreases. What is happening to the substance's mass and volume to cause this decrease in density?
A decrease in density would indicate a reduction in mass relative to the volume. If the mass decreases but the volume remains the same or increases, then the density would decrease.
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
How can you find the density of a substance?
I would do it the same way Archimedes did; Weigh the substance, then immerse it in a substance that would not affect it, i.e. water, alcohol, etc., to determine the volume of the sample of the substance, then divide the weight by the volume and reduce the result to grams/cubic centimetre, or whatever unit is convenient; g/cc kg/L tonne/hectolitre, etc., etc. OR: Measure the mass and volume of the substance, then divide the mass by the volume
What would you use to measure density?
The density of a substance is the ratio of its mass to its volume. So, I would measure the mass and volume of a substance to calculate density.
How would you calculate the density of a substance?
Density = Mass/Volume so you need to measure the mass of the substance and divide by the volume that it occupies.
Which substance would be measured in milligrams?
medicine
What would you measure in kg?
mass of a substance or an object
What is the mass of one milliliter?
A milliliter is a unit that is used to measure liquid volume. The mass of one milliliter of a substance would vary greatly depending on the substance.
If mass increases and volume stays the same then density?
no density would increase, mass = volume x density if we assume that the volume of the substance cannot change then the only way to increase mass would be if that substance became more dense.
What is the unit for amount of substance in cgs system?
If you mean the mass, that is the gram.If you mean the mass, that is the gram.If you mean the mass, that is the gram.If you mean the mass, that is the gram.
What has the mass number of 41?
The substance would be an Isotope of the element Potassium.
How do you calculate the density of a substance?
Density is the mass of a substance divided by the volume of that same mass of substance.

When you divide the mass of a substance by its volume you get its what?
When we divide the mass of a substance by its volume we get its density.
Where would a person have the least amount of mass at sea level or the moon?
Neither. Mass, is your total amount of substance, mass never changes.
