Question

If a liquid has a density of 4.3 g/mL, how many molecules are in 2.3L (The molar mass is 200 g/mol)

Answer 1

Knowing the moles of the given sample, we can now calculate the number of molecules by using Avogadro's number (6.022×1023) ( 6.022 × 10 23 ) . The answer is 7.71×1022H2Omolecules 7.71 × 10 22 H 2 O m o l e c u l e s .
