MASS MOLES NUMBER OF PARTICLES

Anika Bradley-5

(0.79g*3)2.37 mol of O

(gram of compound*avogadros number/101.105) 4.7558*10^23 atoms of N

(moles=gram of compound/molar mass of compound)= 80g KNO3/101.105 g/mol= 0.791256614 mol

In 8mol of P2O5 there are 640g of O, 2.408*10^25 atoms of O, 16mol of P (16g*5 atoms *8mol =640) (8mol *5 atoms* 6.02*10^23 =2.408*10^25) (8mol * 2atoms =16)

Zahirah Flowers-1

15 mole S=480g

15x32/1=480g

mol of li= 0.905mol of li

(0.905*6.02x10^23)=5.4481x10^23g of N

((0.905x2)x6.02x10^23)=1.0862x10^24 atoms of O

23x0.998 =22.954 g of Na

Kailan Burgess-2

0.35 mole Ca=2.107x10^23

1 mole=6.02x10^23 0.35 mole=2.107x10^23

K.B and Z.F -3

23x0.998 =22.954g of Na

0.998mol of Na

(0.998 x6.02x10^23)= 6.00769x10^23 atoms of N

14x6.02x10^23 =8.428x10^24 atoms of N

0.998x23 =22.954 mole of Na
