Question

oblicz masy czasteczkowe nastepujacych substacji:H2SO3,Cl2O7,P4

Answer 1

H2SO3

2+32+(3x16)=82u

 

Cl2O7

(2 x 35,5) + (7x16)=183u

 

P4

31x4=124u

Answer 2

MH = 1u

MS= 32u

MO= 16u

MP= 31u

MCl= 35,5u

 

H₂SO₃ = 2MH + MS + 3MO = 2 + 32 + 3×16 = 34 + 48 = 82u

 

Cl₂O₇ = 2MCl + 7MO = 2 × 35,5 + 7 × 16 = 70 +112 = 183u

 

P₄ = 4MP = 4 × 31 = 124u

 

 

Answer 3

mH₂SO₃=2 x 1u + 1 x 32u + 3 x 16u=82u

mCl₂O₇= 2 x 35,5u + 7 x 16u =183u

mP₄= 4 x 31u=124u
