`27 g` of `Al` will react completely with…… `g` of `O_(2)`

A

(a)8 g

B

(b)16 g

C

(c )32 g

D

(d)24 g

Text Solution

Verified by Experts

The correct Answer is:
D
`4 Al+3O_(2)rarr2Al_(2)O_(3)`
At. Wt. of `Al=27`
Thus `4xx27 g` of Al reacts with oxygen`=3xx32 g`
`:. 27 g` of Al reacts will oxygen`=(3xx32)/(4xx27)xx27=24 g`.
