A Current of 9.65 ampere flowing for 10 minutes deposits 3.0g of the metal which is monovalent. The atomci mass of the metal isA. 10B. 50C. 30D. 96.5 |
Answer» Correct Answer - 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 |
