Question

Cât se poate de repede,Dau coroană​

Answer 1

Răspuns:

Masele molare

Explicație:

Masele:

H2SO4= 2*1+1*32+4*16=2+32+64=98g/mol

HClO=1*1+1*35,5+1*16=1+35,5+16=52,5g/mol

HClO4= 1*1+1*35,5+4*16=1+35,5+64=100,5g/mol

Mn3(PO4)2=3*55+2*31+8*16=165+62+128=355g/mol

H2C2O4=2*1+2*12+4*16 =2+24+64=91g/mol

Raportul atomic:

H2SO4 -> 2:1:4

HClO -> 1:1:1

Mn3(PO4)2 -> 3:2:8

H2C2O4 -> 2:2:4

HClO4 -> 1:1:4

Raportul de masa :

H2SO4=2:32:64

HClO=1:35,5:16

HClO4=1:35,5:64

Mn3(PO4)2=165:62:128

H2C2O4=2:24:64
