Find the formula weight of "Ca"("C"_6"H"_12"NO"_3"S")_2Ca(C6H12NO3S)2?

1 Answer

396396

Explanation:

Relative atomic masses: of:

Ca = 40Ca=40

C = 12C=12

H = 1H=1

N = 14N=14

S = 32S=32

O = 16O=16

So

= 40 + [(12 xx 6) + (1 xx 12) + 14 + 32 + (16 xx 3)] xx 2=40+[(12×6)+(1×12)+14+32+(16×3)]×2

= 40 + [72 + 12 + 14 + 32 + 48] xx 2=40+[72+12+14+32+48]×2

= 40 + 178 xx 2=40+178×2

= 396=396
