Answer:
The correct answer is B) 2 x (98g)
Explanation:
We calculate the weight of 1 mol of H2S04, from the atomic weights of each element obtained from the periodic table.
Weight 1 mol H2S04= (Weight H)x2 + Weight S + (Weight 0) x4
Weight 1 mol H2S04= 1 g x 2 + 32g + 16 g x 4= 98 g/mol
1 mol-------------------98 g H2S04
2 mol------------------x= (2 mol x98 g H2S04)/1 mol= 196g
