Question

amount of hydrogen gas released when 1.5 moles of methanol and 2 moles of aluminium are made to react with each other is
(1) 3/2 mole
(2)3/4 mole
(3)1/3 mole
(4)1/4 mole​

Answer 1

Answer:

Correct option is

B

112 cm

From the above equation we can say than 2 mole of Methanol gives 1 mole of Hydrogen gas.

So now, 0.016g methanol means 0.01 mole of methanol which will give 0.005 mole of hydrogen.

Under STP condition 1 mole gase =22.4L

0.005 mole Hydrogen=22.4X0.005L=0.112L=112 cm
