Question

the molar mass of any substance is equivalent to its atomic or formula weight in _____________.
atomic mass units (amu)
quantum mass units (qmu)
stoichiometric mass units (smu)
empirical mass units (emu)
question 12
1 pts
one mole of carbon weighs _____________ and contains 6.022××10²³ carbon atoms.
12.01 grams
12.01 milligrams
12.01 kilograms
12.01 pounds

Explanation:

Brief Explanations

The molar mass of a substance has the same numerical value as its atomic or formula weight, but the unit is grams per mole. The atomic mass unit (amu) is used for the mass of individual atoms or molecules on a relative - scale. One mole of carbon has an atomic weight of approximately 12.01 amu on the atomic - mass scale, and when considering molar mass, one mole of carbon weighs 12.01 grams.

Answer:

For the first question: atomic mass units (amu)
For the second question: 12.01 grams
