Question

how many gram of H2 S o4 are present in 0.25 mole of H2 s o4

Answer 1

First, find the molar mass of H2SO4 by adding up the molar masses of each individual element. The total is 98.08 grams, so a mole of H2SO4 has a mass of that much. 0.25 moles of H2SO4 would therefore have a mass of a quarter of 98.08, or 24.52 grams.

Answer 2

Since no. Of moles = weight in gold ÷ molecular weight  Since molecular weight of h2so4 = 1×2+32+16×4 = 98 Hence weight in gold of h2so4 = no. Of moles × molecular weight  =.25× 98 =254. 5 g
