1Obliczile atomów znajduje sie w 10g wapnia.
2Ile moli zawiera 12g wodoru czasteczkowego.
1)
mCa=40u
40g Ca-------6,02*10^23 at. wapnia
10g Ca---------x at. wapnia
x = 1,505*10^23 at. wapnia
2)
M H2=2g/mol
2g H2------1mol
12g H2------xmoli
x = 6moli
1. x at - 10g
6,02*10 do 23-40g
x =(6,02*10do 23*10)/40=1,5*10 do 23
2. 12g -x mola
2g-1 mola
x=(12*1)/2=6
