Answer 1

mO₂=16u*2=32u

mCl₂=35,5u*2=71u

mNH₃=14u+3*1u=17u

mO₃=3*16u=48u

mI₂=127u*2=254u

mCaCl₂=40u+2*35,5u=40u+71u=111u

mK₂CO₃=2*39u+12u+3*16u=78u+12u+48u=138u

mCuSO₄=64u+32u+4*16u=96u+64u=160u

mAgNO₃=107u+14u+3*16u=121u+48u=169u

mAl₂S₃=27u*2+32u*3=54u+96u=150u

Na₂SO₃=23u*2+32u+3*16u=46u+32u+48u=126u

Mg(NO₂)₂=24u+2*14u+4*16u=24u+28u+64u=116u

mCa₃(PO₄)₂=40u*3+2*31u+8*16u=120u+62u+128u=310u

mKBr=39u+80u=119u

mCaSO₄=40u+4*16u+32u=40u+64u+32u=104u+32u=136u

mFeSO₄=56u+32u+64u=152u
