Question

Find the volume of hydrogen gas formed when 1.5g of aluminum reacts with aq NaOH at 27 degrees Celcius.

Answer 1

Answer:

1.33litres

Explanation:

number of moles of aluminum is 1.5/27

comparing mole ratio of between aluminum and hydrogen which is 1:1, the moles of hydrogen is also 1.5/27,

volume of hydrogen at 27 degrees Celsius (room temperature) is 1.5/27*24litres= 1.33 litres
