Answer 1

Ответ:

Mr(Cl2)=2×35.5=71, Mr(O3)=3×16=48, Mr(P4)=4×31=124, Mr(CO)=12+16=28, Mr(H2S)=1×2+32=34, Mr(H3PO4)=1×3+31+16×4=98, Mr(CO(NH2)2)=12+16+2(14+1×2)=28+2×16=60, Mr(C6H12O6)=12×6+1×12+16×6=72+12+96=180, Mr(C3H5(OH)3)=12×3+1×5+3(16+1)=41+3×17=92, Mr(Na3PO4)=23×3+31+16×4=70+64=134, Mr(Al(OH)3)=27+3(16+1)=27+51=78, Mr(Ba(NO3)2)=137+2(14+16×3)=137+2×62=261, Mr(Al2(SO4)3)=27×2+3(32+16×4)=54+3(32+64)=54+3×96=342, Mr(Mg3(PO4)2)=24×3+2(31+16×4)=72+2×95=262, Mr(Al2(CO3)3)=27×2+3(12+16×3)=54+3×(12+48)=54+60=114, Mr(Ca(OH)2)=40+2(16+1)=40+34=74, Mr(Pb(NO3)2)=207+2(14+16×3)=207+2×62=331, Mr(Zn(OH)2)=65+2(16+1)=65+34=99
