How many chloride ions are present?
The number of chloride ions present in a given substance depends on the substance size and the type of substance.
Which is not true about the chemical formula of a substances?
which is not true about the chemical formula of a sbstance? a.it gives the number and kinds of atoms present. b.it shows that a substance has a definite compound. c.it shows the elements present in the compound. d.it shows the phase of a substance.
How is the coefficient used to count the number of atoms in a substance?
The coefficient in a chemical formula represents the number of moles of each substance involved in a reaction. By using the coefficients in a balanced chemical equation, you can determine the ratio of atoms between the reactants and products, allowing you to calculate the number of atoms present in a substance.
How many representative particles are in 1.45 g of a molecular compound with a molar mass of 237 g?
1.45 g of a molecular compound with a molar mass of 237 represents 1.45/237 or 6.118 X 10-3 mole. Assuming that "representative particles" in the question means "molecules", this is (6.118 X 10-3){Avogadro's Number} or 3.68 X 1021 molecules.

What is the SI unit used to measure the number of representative particles in a substance?
its the mole.
What is the smallest number written to the right of a chemical equation?
The smallest number written to the right of a chemical equation is the coefficient, which represents the number of molecules or formula units of a substance involved in the reaction.
What is the smallest number of species that can be present in a food chain that includes a carnivore?
four
What is the smallest number of electoral votes a state can have?
Each state has electoral votes equal to the total of the 2 representative the state has in the U.S. Senate plus the number of representative the state has in the House of Representatives. Since every state has two senators and at least one representative to the House, every state has at least 3 electoral votes.
What does avogadro's number tell you?
It gives the number of atoms or molecules of a substance which will be present in one mole.
What is meant by the Avogadro number and why is it relevant to the mole?
Avogadro's number is the number of atoms or molecules of a substance that are present in one mole of that substance. It is relevant to the mole by its very definition!
How many lb-moles of substance are present in the given sample?
To determine the number of lb-moles in a sample, divide the weight of the sample in pounds by the molecular weight of the substance. This will give you the number of lb-moles present in the sample.
Smallest particle of a substance that is still identifiable as that substance?
An atom, these include protons, neutrons and electrons. The number of these smaller particles is what distingushes one atom of an element for another. For example, an atom of oxygen has 8 protons, neutrons, and electrons while a hydrogen atom has 1 proton neutron and electron
How do you calculate the molar volume of a substance?
To calculate the molar volume of a substance, you divide the volume of the substance by the number of moles present. This can be done using the formula: Molar Volume Volume / Number of Moles.
