Q. 0.005 cm thick coating of silver is deposited on a plate of $4728.6 A o$ area. The number of silver atoms deposited on the plate are (atomic mass of $6172.8 A o$ and its density $25^{o} C$ )

$600^{o} C$

$C_{p} = 5.006 + 0.0026 T$

$138 c a l / d e g$

$13.75 c a l / d e g$

Volume of Ag deposited $I < I V < II < III$ Mass of Ag deposited = Volume $I < III < II < I V$ density Hence, number of Ag atoms deposited $I > III > I V > II$ $F e C r_{2} O_{4} I N a_{2} C r O_{4} II C r_{2} O_{3} III C r$ $N a O H / ai r$
