Question

Q- Calculate the mass of dioxygen required to react with 27 g Al to form Al2O3. please very urgent. ​

Answer 1

Answer:

Mass of Al=27g

Mass of O2=32g

Balanced chemical equation:

4 Al  +  3 O2   ---------->  2 Al2O3

Mole ratio of Al :O2 = 4 : 3,

which is 1 : 3/4

Mass of O2 required = 3/4 * 32g

                                   =24g
