# What is the mass of oxygen in 250 g of sulfuric acid, H2SO4 [Solved] 10.19565 moles x (16 g / 1 mole) = 163.13 grams

Molecular Weight of Oxygen = ~16 g/mole

Molecular Weight of Oxygen = ~16 g/mole

Molecular Weight of Oxygen = ~16 g/mole

No because if you do that to the other elements it doesnt add upto 250g.
Find the RMM of H2SO4 then divide the actual mass by the RMM.
So yu get bout 2.5 moles of H2SO4 then times 64 by 2.5 and you have your answer i think.

10.19565 moles x (16 g / 1 mole) = 163.13 grams

H = 1.008 (x2) S = 32.065 O = 16 (x4)
(21.008) (132.065) (164) = ~ 98.081 g/mole

4) Determine the mass of oxygen in 10.19565 moles of oxygen.

Answer = 163.13 grams of oxygen in 250 grams of sulfuric acid

10.19565 moles x (16 g / 1 mole) = 163.13 grams

10.19565 moles x (16 g / 1 mole) = 163.13 grams

10.19565 moles x (16 g / 1 mole) = 163.13 grams

Answer = 163.13 grams of oxygen in 250 grams of sulfuric acid

H = 1.008 (x2) S = 32.065 O = 16 (x4)
(21.008) (132.065) (164) = ~ 98.081 g/mole

4) Determine the mass of oxygen in 10.19565 moles of oxygen.

3) Determine the number of moles of oxygen in 2.5489 moles of sulfuric acid. This can be determined by finding the ratio of oxygen to sulfuric acid. For every 1 mole of sulfuric acid, there are 4 moles of oxygen. Thus:
