Acertain material has a mass of 565 g while occupying 50 cm3 of space. what is this material?

the material is Lead (Pb) .

you can get it by this steps:

1) first, we need to find the density:

when the denisty formula is = mass/volume.

and when we have the mass = 565 g, and volume is 50 Cm^3 . so, by

substitution: denisty = 565 g / 50Cm^3 = 11.3 g /Cm^3 . then after we get the

density of the material, we can look at the periodic table and serach for the

denisty which match the density result and find the element matching that

denisty. so our material here is lead as the denisty of lead is 11.34 g/Cm^3.

It is 4.92 e-4 sorry if i am wrong
