What is the mass of oxygen in 350 g of sulfuric acid h2 s04

228,585 gram

Explanation:

M h2so4 = 2 + 32 + 16*4 = 98 g/mole

C% o2 in h2so4 = (64 / 98) * 100 = 65,31%

m o2 = 350 * 65,31% = 228,585 gram

Done :))

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
