3.7 Summary of Inorganic Nomenclature
The formula mass is the sum of all the atoms in a compound's chemical formula.
The formula mass of carbon dioxide is: x Multiply by 2 because it has two oxygen atoms.
Multiply by 2 because the formula has two sodium atoms.
C6H12O6 has a formula mass.
Add the atomic mass of each atom to the chemical formula to find the formula mass.
The element's mass in grams of one mole of its atoms is numerically equivalent to its atomic mass.
The number of atoms in a given mass of the element can be determined using the molar mass and Avogadro's number.
The same concept can be applied to compounds.
The mass in grams of 1 mol of its molecule is equivalent to the formula mass.
The formula mass of CO2 is 44.01.
The molar mass of CO2 is 44.01 g/mol.
The number of CO2 molecule in a sample of dry ice with a mass of 10.8 g is similar to the number of atoms in a sample of copper.
The mass of the compounds can be used to convert the amount in moles.
Avogadro's number is used to convert to number of molecules.
We follow the conceptual plan, beginning with 10.8 g CO2, converting to moles, and then to Molecules.
acetylsalicylic acid is found in an aspirin tablet.
The units of the answer are correct.
Since you have less than 1 molar mass of acetylsalicylic acid, the magnitude is smaller.
You can find the number of ibuprofen molecules by looking at the tablets.
Determine the mass of the sample of water.
