Answer 1

To calculate the number of molecules in 2 moles of the food coloring C18H12, multiply Avogadro's constant by 2.

Step-by-step explanation:

To calculate the number of molecules in 2 moles of the food colouring C18H12, we need to use Avogadro's constant. Avogadro's constant is 6.02 x 1023 molecules per mole. Since we have 2 moles, we can multiply the Avogadro constant by 2 to get the total number of molecules.

Number of molecules = 2 moles x 6.02 x 1023 molecules per mole

Number of molecules = 1.204 x 1024 molecules
