The mass of an atom of carbon-12 is 1.993 × 10⁻²³ g.

1 C atom has a mass of 12 u.

1 mol of C atoms has a mass of 12 g.

∴ Mass of 1 C atom = 12 g/6.022 × 10²³ C atoms = 1.993 × 10⁻²³ g

The molecular formula of morphine, a pain-killing narcotic, is c17h19no3. what is the molar mass? what is the mass of 6.02 x 102
kati45 [8]
<span>Molar mass is the mass of one mole of a substance, it can be a chemical element or a compound. It is a characteristic of each pure substance. We calculate it by adding up all of the masses of the atoms involved in the compound. We calculate as follows:
                   atomic mass         total mass
C     17        12.01 g/mol          204.17 g/mol
H     19          1.01 g/mol           19.19 g/mol
N      1         14.00 g/mol            14.00 g/mol
O      3         16.00 g/mol            48.00 g/mol
------------------------------------------------------------
Molar mass                           = 285.36 g/mol

</span><span>What is the mass of 6.02 x 10^24 molecules of morphine?

</span>6.02 x 10^24 molecules ( 1 mol / 6.02x10^23 molecules) ( 285.36 g/mol) = 2853.6 g morphine
