Answer:
4 moles, 160 g
Explanation:
The formula for the calculation of moles is shown below:
For :-
Mass of = 196 g
Molar mass of = 98 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the given reaction:
1 mole of sulfuric acid reacts with 2 moles of NaOH
So,
2 moles of sulfuric acid reacts with 2*2 moles of NaOH
Moles of NaOH must react = 4 moles
Molar mass of NaOH = 40 g/mol
<u>Mass = Moles*molar mass = = 160 g</u>
