5 ng per microlitre is how many ppm?
You need to tell us what substance you want to convert.So we can calculate the molar mass.
What does atomic mass number tell us?
The atomic mass number tells us the total number of protons and neutrons in an atom's nucleus. It is used to determine the mass of an atom and is necessary for calculating the atomic weight of an element.
What does the molar mass of an element or compound tell you?
How many grams of the substance are in a mole of the substance. The molar mass of Carbon, for example, is 12 g/mol. This means that every 6.02*10^23 atoms mass 12 grams.
What is the mass if the volume is 25cm cubed?
You would have to know the density also. Mass = volume X density
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.
What is the relationship between the dimension of molar mass and its significance in chemical calculations?
The molar mass of a substance is the mass of one mole of that substance. It is important in chemical calculations because it allows us to convert between the mass of a substance and the number of moles present. This relationship is crucial in determining the amount of reactants needed or products formed in a chemical reaction.
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 determines the density of a substance?
The density of a substance is determined by its mass and volume. Density is calculated by dividing the mass of the substance by its volume. The denser a substance is, the more mass it has in a given volume.
Why is mass imp?
because mass is the total amount of quantity of a substance. mass helps to retain the substance
What is the Mass of an object divided by amount of substance?
(Mass) divided by (Volume) is defined as the density of the sample or object.
When you divide the mass of a substance by it volume you get what?
When we divide the mass of a substance by its volume we get its density.
How do you find mass of a substance?
Use a scale or a balance to measure the mass of the substance.
