Question

1. Which of these weighs most?
(1) 32 g oxygen
(2) 2 g atom of nitrogen
(3) 0.5 mole of iron
(4) 3.01 * 1023 atoms of carbon the answer is1 please give explanation​

Answer 1

Answer:

answer is 1

Explanation:

Oxygen's atomic weight is 16.00 amu. 1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the molar mass (g/mole) ofoxygen? Molar mass (in grams) is always equal to the atomic weight of the atom! Molar mass (in grams) is always equal to the atomic weight of the atom!
