Calculate the mass of 2.5-gram atoms of oxygen.
Gram atomic mass:
Given
Therefore, the mass of 2.5-gram atoms of oxygen is 40g.
Calculate the number of (a) Oxygen atoms in 0.10 mole of Na2CO3. 10H2O (b) gram atoms in 4.6 gram of sodium.
If one mole of oxygen atoms weighs 16 grams, calculate the mass of one atom of oxygen (in grams).
