CBr4 , this is the correct formula for carbon-tetra-bromide
The molecular mass of CBr4 is 12.0 + 4(79.9) = 331.6Amount of CBr4 = mass of substance / molecular mass = 393/331.6 = 1.19mol This means that a 393g pure sample contains 1.19 moles of tetrabromomethane. The Avogadro's number is 6.02 x 10^23 So, number of molecules of CBr4 = 1.19 x 6.02 x 10^23 = 7.13 x 10^23

No. CBr4 is nonpolar and H2O is polar. Both do not mix.
No, it is not.
No CBr4 is covalent.
