1) I’m going to do a lot of rounding…but…you’ll get the point

4800L x 1mol/22.4L = 214.286 mol of H2

Since you lose 20%, do 214.286 x .20 = 42.8

Add 214.286 + 42.8 = 257 mol of H2

For Iron:

257 mol H2 x 1 mol Fe/1 mol H2 = 257 mole Fe

257 mol Fe x 55.85 g Fe/1 mole Fe = 14,300ish grams Fe

For H2S04:

257 mol H2 x 1 mol H2So4/1 mol H2 = 257 mole H2SO4

257 mol H2SO4 x 98 g H2SO4/1 mole H2SO4 = 25,000ish grams H2SO4

I might be off by a decimal place or something…but other than that, i’m pretty sure i’m right…unless i interpreted the question differently

2)

I’ll do later maybe.
