Answer 1

Odpowiedź:

mSO3= 32u+ 3×16u= 32u+ 48u= 80u

mHNO3= 1u+ 14u+ 3×16u= 1u+ 14u+ 48u= 63u

mH2SO3= 2×1u+ 32u+ 3×16u= 2u+ 32u+ 48u= 82u

mBa(OH)3= 137u+ 3×16u+ 3×1u= 137u+ 48u+ 3u= 188u

mNa2CO3= 2×23u + 12u+ 3×16u= 46u+ 12u+ 48u= 106u

mPb3(PO4)2= 3×207u+ 2×31u+ 8×16u= 621u+ 62u+ 128u= 811u

mC3H7COOH= 4×12u+ 8×1u+ 2×16u= 48u+ 8u+ 32u= 88u

mAl2(SO4)3=2× 27u+ 3×32u+ 12×16u= 54u+ 96u+ 192u= 342u

mC2H5OH= 2×12u+ 6×1u+ 16u= 24u+ 6u+ 16u=46u
