Answer 1

Explanation:

the answer of balanced equation is-

2NaOH +H2SO4 gives 2H2O+ Na2SO4

40 is the molar mass of NaOH, 142 is the molar mass of Na2SO4, 18 is molar mass of water

a) mNaOH = 40g/mol

mNa2SO4= 142 g/mol

nNaOH/nH2O= 2/1

200×18/x×40= 2

200×18/40×2= x

90/2=45

b) 200/40/x/142

=200×142/40×2=x

355 grams.

c) H2SO4/Na2SO4=2/1

2.5×142=101×x

355=101×x

x=355/101

x=3.51 g
