1.6g of a trivalent metal were dissolved in `HNO_(3)` to form its nitrate. If the nitrate on heating produces 2.4 g of metal oxide then atomic mass of metal is

A

0.16

B

0.48

C

24

D

31

Text Solution

Verified by Experts

The correct Answer is:
B
`overset(1.6g)(M)toM(NO_(3))_(3)tooverset(2.4g)(M_(2))O_(3)`
PoAC for M
`(1xx1.6)/M=(2xx2.4)/(2M+48)`
`3M=2M+48impliesM=48`
