Answer: 2Na+2H2O------>2NaOH+H2

b) From the equation two moles of sodium gave one mole of hydrogen.

At stp the volume of hydrogen is 22400cm3.

The molar mass of sodium is 23

So we have

2molesNa--->1moleH2

5.76moles--->? mole H2

Meaning

2(23)Na----> 22400cm3 ofH2

5.67Na---->?H2

22400×5.67÷ 2(23)

127008÷46=2761.04cm3

Sorry I can't do the last one.
