How many atoms of chlorine are in 310g of carbon tetrachloride?

4.84 x 10²⁴ atoms.

Explanation:

∴ The no. of carbon tetrachloride (CCl₄) molecules  = no. of moles x NA = (2.015 mol) (6.022 x 10²³) = 1.21 x 10²⁴ molecules.

∴ The no. of chlorine atoms in 310 g of carbon tetrachloride (CCl₄) = 4 x 1.21 x 10²⁴ = 4.84 x 10²⁴ atoms.

is there multiple choice answers?

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
