Some molecules such as iodine have two atoms to make up the substance, while others have thousands. A molecule of sugar has 45 atoms to make up the substance. If a sugar crystal has 1000 molecules, how many atoms are present?

45000 atoms

Explanation:

From the question given above, we were told that a molecule of a sugar is made up of 45 atoms. This implies that:

1 molecule of sugar = 45 atoms

With the above idea in mind, we can obtain the number of atoms present in 1000 molecules of the Sugar as follow:

1 molecule of sugar = 45 atoms

Therefore,

1000 molecules of sugar = 1000 × 45 = 45000 atoms.

Therefore, there are 45000 atoms present in 1000 molecules of the sugar.

i wish i could but this one is weird give me abc and i can solve it.
