Calculate the number of molecules in 15.7 mol carbon dioxide.

Hey there!

One mole has 6.022 x 10²³ molecules.

We have 15.7 moles, so multiply.

15.7 x 6.022 x 10²³ = 9.45 x 10²⁴

There are 9.45 x 10²⁴ molecules in 15.7 moles of carbon dioxide.

Hope this helps!

im pretty sure its b

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
