Answer 2

Answer:

Given molarity and volume ..

you can find out the moles of H2SO4 -

= 0.3×200 = 60 millimoles

now clearly 2 moles of NaOH are required for 1 mole of H2SO4.

So moles of NaOH required = 120 millimoles

hence mass = 120 × 40

= 4800 mg

= 4.8g

Hope it helps you..

just let me know if you have any dóubt
