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

i just learnt this recently but i need to look through my notes again

they are made of gases.

they have a spherical shape.

they make energy through fusion.
