1 It was found that 4n atoms of metal x
raketka [301]

Answer:

C 108

Explanation:

1 It was found that 4n atoms of metal x

weigh 501.6 g. The relative atomic mass

of X is 209. If n atoms of another metal,

Y, weigh 65.00 g, what is the relative

atomic mass of metal Y?

A 27 B 52 C 108 D 137

if 4n atoms of x weigh 501.6 gm, the n atoms weigh 501.6/4 = 125.4 gms

since the atomic mass is 209, then 6.022 X10^23 atom weigh 209

the ratio of 125.4 to 209 is

125.4/Y =0.6

therefor n is the number of atom in 0.6 moles

if metal Y has the same, number of atoms "n"  and weighs 65 gm

then then the relative atomic mass is

65/0.6 =108

so the answer is

C 108
