Question

A quantity of Lithium reacts with sulfuric acid (H2SO4) to produce .10 g of hydrogen. How many grams of lithium are required ?

Answer 1

Answer:

0.35 g Li

Explanation:

H2SO4 + 2Li -> Li2SO4 + H2

7 g Li -> 2 g H2

      x  -> 0.10 g H2

x= (0.10 g H2 * 7 g Li)/ 2 g H2      x= 0.35 g Li
