The molar mass of elements, found on the periodic table, is measured in grams. This is because molar mass refers to the mass of one mole of a substance, and the unit for measuring mass in the SI system is grams.
To determine the molar mass of an element, you can look at the periodic table. Each element is listed with its atomic symbol and atomic mass. The atomic mass of an element is the average mass of all its isotopes, taking into account the abundance of each isotope.
For example, the atomic mass of carbon is approximately 12.01 amu (atomic mass units). This means that one mole of carbon atoms has a mass of approximately 12.01 grams. Therefore, the molar mass of carbon is 12.01 grams/mol.
It's important to note that the unit "amu" (atomic mass unit) is used to express atomic mass, not molar mass. Molar mass is always expressed in grams/mol. So, in this case, the correct answer is C. grams.
