Question

How many grams of concentrated sulphuric acid (80% w/w) should be used to prepare 100 ml of one molar h2so4 solution?

Answer 1

$\huge {ans\space brother}$

grams of compound needed = (1 N)(49)(0.250 liters) = 12.25 grams. If you took 6.9 mL of concentrated sulfuric acid and diluted it to 250 mL, you would have a 1 N H2SO4 solution. (Important note: Always add the acid (or base) to water, in that order.
