Question

Oblicz masę cąsteczkową danych związków chemicznych:

a.NaOW

b.Na2O

c.SO2

d.H2So4

e.AllOH3

f.CaCO3

g.CuSO4 * 5H2O

Answer 1

a. 23 u+16u+(wolfram?) + 183u = 222u

b. 23u+23u+16u = 62 u

c. 32u+ 16u+16u=64u

d. 2u+32u+64u= 98u

e.All ?

f. 40u+12u+3*16u=100u

g. 63u+32u+*16u* 5(2*1u+16u) = 201u

Answer 2

NaOW = 23u + 16u + 184u = 223u

Na2O = 23u*2 + 16 = 62u

SO2 = 32u + 16*2 = 64u

H2SO4 = 1*2 + 32u + 16u*4 = 98u

AlIOH3 = 27u + 127u + 16u + 1*3 = 173u

CaCO3 = 40u + 12u + 16u*3 = 100u

CuSO4 = 64u + 32u + 16*4 = 160u
