Question

How many sugar molecules are in 1 grain of sugar?

Answer 1

Answer:

As you said, Avogadro's Number is 6.022 x 1023 molecules per mole, so a single grain of sugar contains 1.09954 x 1018 molecules of sucrose, or 1.1 quintillion molecules per grain of sugar (in American terms).

Answer 2

Answer:

So, one grain is 1.82588 x 10-6 moles or around 1.8 µM (micromoles). As you said, Avogadro's Number is 6.022 x 1023 molecules per mole, so a single grain of sugar contains 1.09954 x 1018 molecules of sucrose, or 1.1 quintillion molecules per grain of sugar (in American terms).
