A current of 9.65A flowing for 10 minutes deposits 3.0g of the metal which is monovalent. The atomic mass of the metal is

A

10

B

50

C

30

D

96.5

Text Solution

Verified by Experts

The correct Answer is:
B
`Q="If"=9.65xx10xx60=5790C`
` underset("monovalent metal") (M^(+))+underset("IF" 96500C)(e)rarrunderset("1mole")(M)`
With 5790C , amount of metal depsoited=3gm
With 96500C, amount of metal deposited.
`=(3)/(5790)xx96500`
=50 g (equivalent weight)
Atomic mass=`50xx` valency=`50xx1=50` amu
