Review of Calculating Molecules Lesson 10

Calculate the number of H atoms in C12H24N2SO3 if there are 144 C atoms. 144 at C x 1 molecule x 24 at H = 288 at H 12 at C 1 molecule Calculate the number of C atoms in C12H24N2SO3 if there are 240 H atoms. 240 at H x 1 molecule x 12 at C = 120 at C 24 at H 1 molecule

Calculate the mass of C12H24N2SO3 if there are 8.00 x 10 22 H atoms. 8.00 x 1022 at H x 1 molecule x 1 mole x 276.34 g 24 at H 6.02 x 1023 molecule 1 mole = 1.53 g Calculate the mass of C12H24N2SO3 if there are 4.00 x 10 22 C atoms. 4.00 x 1022 at C x 1 molecule x 1 mole x 276.34 g 12 at C 6.02 x 1023 molecule 1 mole = 1.53 g
