Question

Tính PTK của các hợp chất có CTHH sau: BaSO₄, Fe(OH)₃, Na₂SO₃, Al₂(SO₄)₃, C₁₂H₂₂O₁₁, Ca(NO₃)₂.
Ghi rõ cách tính giúp mik vs ạ. Cảm ơn

Answer 1

\(-PTK_{BaSO_4}=137+32+16.4=233\left(đvC\right)\)

\(-PTK_{Fe\left(OH\right)_3}=56+\left(16+1\right).3=107\left(đvC\right)\)

\(-PTK_{Na_2SO_3}=23.2+32+16.3=126\left(đvC\right)\)

\(-PTK_{Al_2\left(SO_4\right)_3}=27.2+\left(32+16.4\right).3=342\left(đvC\right)\)

\(-PTK_{C_{12}H_{22}O_{11}}=12.12+1.22+16.11=342\left(đvC\right)\)

\(-PTK_{Ca\left(NO_3\right)_2}=40+\left(14+16.3\right).2=164\left(đvC\right)\)
