What would be the mass of a 45 cm^3 cube of uranium?

m = 859.5  g

Explanation:

d (Uranium) = 19.1 g/cm3

V = 45 cm3

m = V × d = 45 × 19.1 = 859.5  g

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
