VA ROG REPEDE​

Answer 1

Răspuns:

Explicație:

MNa2O=2.23 + 16=62------->62g/moli

MAlPO3=27 +31 +3 .16=106 ------->106g/moli

MBa3( PO4)2=3.137 +2.31 +8.16=601---->601g/moli

MHCl=1+35,5=36,5------>36,5g/moli

MCuO=64+16=80----->80g/moli

MAgCl=108 + 35,5=143,5 -----> 143,5 g/moli

MK3PO4=3.39 +31 +4.16=117 +31+64

                                        =212------> 212g/moli

MSO2=32+2 .16=64------->64g/moli

MCO=12+16=28------->28g/moli

MO2=2.16=32------>32g/moli

MAgNO3=108 +14+3.16=170----->170g/moli
