a) Khoi luong cua khi SO3
mSO3 = nSO3 . MSO3
= 0,25 . 80
= 20 (g)
So phan tu cua khi SO3
A = nA . 6 .10-23
= 0,25 . 6 . 10-23
= 1,5 . 10-23
khoi luong cua khi oxi
mO2 = nO2 . MO2
= 0,5 . 32
= 16 (g)
So mol phan tu cua khi Oxi
A = nA . 6 . 10-23
= 0,5 . 6 .10-23
= 3 . 10-23
Khoi luong cua khi clo
mCl2 = nCl2 . MCl2
= 0,75 . 71
= 53,25 (g)
So mol cuar phan tu khi clo
A = nA . 6 . 10-23
= 0,75 . 6 . 10-23
= 4,5 . 10-23
b) Khoi luong cua khi oxi
mO2 = nO2 . MO2
= 1 . 32
= 32 (g)
So mol cua phan tu khi oxi
A = nA . 6 . 10-23
= 1. 6 . 10-23
= 6 . 10-23
Khoi luong cua khi cacbon monooxit
mCO = nCO . MCO
= 1,5 . 28
= 42 (g)
So mol cua phan tu khi cacbon monooxit
A = nA . 6 . 10-23
= 1,5 . 6 .10-23
= 9 . 10-23
Khoi luong cua khi metan
mCH4 = nCH4 . MCH4
= 0,125 . 16
= 2 (g)
So mol cua phan tu khi metan
A = nA . 6 .10-23
= 0,125 . 6 .10-23
= 0,75 . 10-23
