What is the total number of grams of naoh needed to react completely with 196 grams of h2 so4? regents

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

Mass = Moles*molar mass = = 160 g

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
