What affect would an incorrect reading of temperature have on the molar mass?
An incorrect reading of temperature would not directly affect the molar mass of a substance. Molar mass is a fixed property of a substance regardless of the temperature at which it is measured. Temperature typically affects the physical state and behavior of the substance, but not its molar mass.
How can you determine the density of a substance?
To determine the density of a substance, you would divide the mass of the substance by its volume. The formula for density is density = mass/volume. Measurements should be taken in units such as grams for mass and cubic centimeters for volume.
What is the molar mass of a substance in daltons?
The molar mass of a substance in daltons is the mass of one mole of that substance, measured in daltons.
How can one determine the amount of moles in a given substance?
To determine the amount of moles in a substance, you can use the substance's mass and molar mass. Divide the mass of the substance by its molar mass to calculate the number of moles. This formula is represented as moles mass / molar mass.
What is the volume of a substance with a mass of 36G and volume of 9Cm cubed?
To determine the volume of a substance with a mass of 36g and a volume of 9cm^3, you would need to know the density of the substance. Since density is mass divided by volume, you can calculate it by dividing the mass (36g) by the volume (9cm^3). The density would be 4g/cm^3.
If a trial was done with a volume of 45mL what would the mass be?
You multiply the volume by the density of the substance.
What would you measure in kg?
mass of a substance or an object
How could density be used to determine the mass of a particular volume of a substance?
To determine the mass of a particular volume of a substance using density, you would multiply the density of the substance by the volume of the sample. The resulting value would give you the mass of the substance based on the known density and volume relationship (mass = density x volume).
Which substance would be measured in milligrams?
medicine
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.
How do you determine the substance given the mass?
To determine the substance given the mass, you would need to compare the mass to the known density of various substances. By dividing the mass by the volume (which can be calculated from the dimensions of the object), you can determine the density of the substance. Then, you can compare this density to known values to identify the substance.
What affect would an incorrect reading of temperature have on the molar mass?
An incorrect reading of temperature would not directly affect the molar mass of a substance. Molar mass is a fixed property of a substance regardless of the temperature at which it is measured. Temperature typically affects the physical state and behavior of the substance, but not its molar mass.
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.
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.
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.
A pure radioactive substance has a half-life of 3 hours. How long would it take a mass of 12g of that substance to decay to 3g?
It would take 6 hours for a mass of 12g of the substance to decay to 3g. This can be calculated by recognizing that for every half-life, the mass is halved. So, after 1 half-life (3 hours), the mass would be 6g, and after 2 half-lives (6 hours), the mass would be 3g.
