Unknown metal

The prism made of unknown metal has dimensions of 3 cm by 3 cm by 5 cm and a weight of 121 g. What metal is it? Write its chemical symbol.

Result

x = (Correct answer is: P) Wrong answer

Solution:

a=3 cm b=3 cm c=5 cm m=121 g  V=a b c=3 3 5=45 cm3 m=ρ V ρ=m/V=121/45=121452.6889 g/cm3  Phosphorus  x=P
