How to find the percent by mass of a compound in a given sample?

To find the percent by mass of a compound in a given sample, you need to divide the mass of the compound by the total mass of the sample and then multiply by 100. This will give you the percentage of the compound in the sample.

Is it necessary to know the formula of a compound in order to calculate its percent composition?

No, knowing the formula of a compound is necessary in order to calculate its percent composition. The percent composition is calculated by dividing the mass of each element in the compound by the total molar mass of the compound, which requires knowing the formula to determine the number of atoms of each element present.

Do all pure samples of a given compound have the same percent composition?

Yes, all pure samples of a given compound will have the same percent composition because the percent composition of a compound is a fixed ratio of the elements in that compound. This ratio is determined by the chemical formula of the compound.

How can one determine the molecular formula from the given molar mass and percent composition?

To determine the molecular formula from the given molar mass and percent composition, you can follow these steps: Convert the percent composition to grams for each element present in the compound. Calculate the number of moles of each element using the molar mass and the grams of each element. Divide the moles of each element by the smallest number of moles to get the mole ratio. Use the mole ratio to determine the empirical formula. Calculate the empirical formula mass and compare it to the given molar mass to find the multiplier needed to get the molecular formula.

Is C2H4O2 NaHCO2 a physical change?

No, mixing C2H4O2 and NaHCO2 is not a physical change as it does not alter the chemical composition of the substances involved. It would simply be a physical mixing or dissolution of the two compounds.

How do you know when to solve for a empirical formula?

You should solve for an empirical formula when you are given the percent composition of elements in a compound or when you have the molar mass of the compound but not the molecular formula. The empirical formula provides the simplest whole-number ratio of atoms in a compound.

What is an inducter?

An inductive generalization takes a sample of a population and makes a conclusion regarding the entirepopulation.Inductive Generalizations take the form..X percent of observed Fs are GsthereforeX percent of all Fs are GsFor example, an experiment may test the effects of a drug on lab mice. They might reason..80% of observed mice die when given the drug.therefore80% of all mice die when given the drug.The argument's strength depends on the sample. A sample that is not representative of the population is called a biased sample.
