Answer to Question #309855 in Physical Chemistry for ShiNoHana

Question

How many molecules are in 5 moles of ammonia, NH₃?

Answer 1

n(NH₃) = 5 moles;

N_A(Avogadro constant) = 6.02 * 10²³ mol^-1;

n = N/N_A;

N(NH₃) = n(NH₃) * N_A = 5 * 6.02 * 10²³ = 30.1* 10²³ = 3.01 * 10²⁴ molecules.

Answer: 3.01 * 10²⁴.
