Question

Va rog ajutati-ma dau 25 de puncte ​

Answer 1

Răspuns:

Acid fosforic = H3PO4

Dioxid de carbon = CO2

masa molara H3PO4= 3 + 4*16+ 31 = 98g/mol

masa molara CO2= 12+ 2*16=44g/mol

1 mol = 6.022*10^23 molecule=98g

o molecula H3PO4= 98/(6,022*10^23) grame

o molecula CO2= 44/(6,022*10^23)
