Question

calculate the mass of oxygen produced
please answer fast

Answer 1

Explanation:

MASS OF Al GIVEN = 2000 kg = 2* 10⁶ g

MOLES of Al = 2 * 10⁶/27

ACCORDING TO EQUATION

2 MOLES Al produce ------> 3 moles oxygen

1 moles of Al will produce -----> 3/2 moles of oxygen

HENCE,

2 * 10⁶/27 MOLES OF Al produce -------> 3/2 * 2*10⁶/27. MOLES of oxygen

= 10⁶/9 MOLES OF OXYGEN

= 10⁶/9. * 32/10³ kg of oxygen

= 10³*32/9. kg of oxygen

= 3555.55 kg of OXYGEN
