Question

1) CF2CL2

express answer using two sig figs

how would i solve for this problem???

thanks!

Answer 1

Calculate the molar mass (M)

the atomic mass of Cl is 35.5, so the fraction (by mass) of Cl in M is

2 x 35.5/M

so the mass (in kg) of Cl in CF2Cl2 is

2 x 35.5 x 24/M

Answer 2

1701.6
