The volume occupied by a substance depends on its density. If you know the density of the substance, you can calculate the volume using the formula: Volume = Mass / Density. Without the density information, you cannot accurately determine the volume occupied by 7.75 g of the substance.
What else can I help you with?
When two gases of a chemical reaction are both at the same temperature and pressure and they have the same molar volume what is their stoichiometric ratio in the chemical equation describing the reac?
If the gases have the same molar volume, the stoichiometric ratio would be one to one. Molar volume is the volume occupied by one mole of a substance. This indicates that there is a 1:1 molar ratio of each gas.
Is The density of a substance is the same for all samples of the substance?
Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.
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 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 is the equivalent of 0.0175cu.m in weight?
A cubic meter is a unit of volume, not weight. You would also need to know the density of the substance. For example 0.0175 cubic meters of water will weigh much more than the same volume of air.
What is the volume occupied by 2.12 moles of NO?
The volume occupied by 2.12 moles of nitrous oxide is 9.35. A mole is described in chemistry as an amount of pure substance containing the same number of chemical units as there are atoms.
A cubic meter is about the same as the volume occupied by a what?
A cubic meter is about the same as the space occupied by a washing machine.
What is a substance which has a volume of 1 ml?
Any substance can have a volume of 1cm3, depending on its size (referring to density). For example, 1g of water would have a volume of 1cm3, while 0.8g of ethanol would have the same volume.A substance which has a volume of 1 cm3 is a substance that has a volume of 1 ml. Many substances can have a volume of 1 ml.
What is the volume of liquid?
The volume of a liquid is the amount of space occupied by the liquid.The volume of a liquid is the amount of space occupied by the liquid.The volume of a liquid is the amount of space occupied by the liquid.The volume of a liquid is the amount of space occupied by the liquid.
What volume would be occupied by 7.75g of this same substance?
8:04pm Density = Mass / Volume ...(1) mass = 84.7 gvolume = 49.6 cm³Density = ? g/cm³Part 2:From (1), we havevolume = mass / densityUse mass = 7.75g and density calculated above.part 1: 1.70 g/cm3part 2: 4.55 cm3
Why do two samples with the same substance with the same volume HAVE to have the same mass?
Because they are of the same substance they have the same density density = mass/volume
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.
Is volume the same as matter?
Volume is a size-cubic feet or cubic meters. This volume is the same whether it contains something or is a perfect vacuum containing nothing. Matter just means the presence of atoms of some substance. So the answer is no, they are not the same.
Is the volume of substance the same before and after a fire?
no the volume can be greatly reduced
When two gases of a chemical reaction are both at the same temperature and pressure and they have the same molar volume what is their stoichiometric ratio in the chemical equation describing the reac?
If the gases have the same molar volume, the stoichiometric ratio would be one to one. Molar volume is the volume occupied by one mole of a substance. This indicates that there is a 1:1 molar ratio of each gas.
What would happen to density of a substance whose mass was cut in half?
If the mass of a substance is cut in half but the volume remains the same, the density of the substance would also be cut in half. This is because density is calculated by dividing mass by volume, so reducing the mass will directly affect the density without changing the volume.
Why One mole should represent the same volume?
One mole represents the same number of particles, regardless of the substance. Since the volume that a mole occupies is determined by the substance's molar mass and density, one mole of any substance at the same conditions of temperature and pressure will have the same volume.
