How many lithium atoms are in 4.5 moles of li?

Mwahaha, the sciences, my domain...

The solution to this problem is actually very, very simple.

To find the number of atoms in a given number of moles, we simply multiply by Avogadro's constant.

The value of Avogadro's constant is 6.022 x 10²³

Number of Li atoms = moles x Avogadro's constant

Number of Li atoms = 4.5 x 6.022 x 10²³

Number of Li atoms = 2.7099 x 10²⁴

Number of Li atoms = 2.71 x

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.
