Question

mass of Oxygen present in 10moles of H2S2O8 is​

Answer 1

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) of oxygen? 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!

Answer 2

Explanation:

in one mol H2SO4 there is a 16×8=128 so in 10 is 1280u.
