# How many ATOMS in a #18*g# mass of glucose?

##### 2 Answers

Approx.

where

#### Explanation:

We take the quotient.....

And thus we get an answer with dimensions of

And so we retake the quotient.......

We know that glucose,

We are not finished there, because we were asked to find the number of atoms in such a molar quantity, and there are 24 atoms in one molecule of glucose.

And so we multiply the molar quantity by number of atoms per mole, and then by Avogadro's number to get the number of atoms,

There are

#### Explanation:

One mole of anything is

The molar mass of glucose is

Divide the given mass of glucose by its molar mass by inverting the molar mass (a fraction) and multiply.

Multiply mol glucose by
