how many atoms are in each of the following? a. 1.0g of hydrogen atoms, each of mass 1.0 amu. b. 12.0g of carbon atoms, each of mass 12.0 amu . c. 23.0g of sodium atoms, each of mass 23.0 amu
Homework Answers
a) 1.0 g H = 1.0 mole
1.0 mole = 6.023 x 1023 H atoms
answer = 6.023 x 1023 H atoms
b) 12.0 g C = 1.0 mole C
1.0 mole = 6.023 x 1023 C atoms
answer = 6.023 x 1023 C atoms
c) 23.0 g Na = 1.0 mol Na
1.0 mol Na = 6.023 x 1023 Na atoms
answer = 6.023 x 1023 Na atoms
