Question

Masa moleculara pentru acidurile HNO3, H3PO3, H2SO3, sa fie cu tot cu formule incluse, va rooooogg, cat mai repede !!! DAU STELUTE !!

Answer 1

MHNO3=AH+AN+3×AO

MHN03=1+14+48(3×16)

MHN03=63 u.a.m

MH3PO3=AH×3+AP+3×AO

MH3PO3=3(1×3)+31+48

MH3PO3=82 u.a.m

MH2SO3=2×AH+AS+3×AO

MH2SO3=2+32+48

MH2SO3=34+48=82 u.a.m

Answer 2

HNO3

M=AH + AN + 3AO=1+14 + 3.16=63-----> 63g/moli HNO3

H3PO3

M= 3AH + AP + 3AO= 3 + 31 + 3.16=82--------> 82g/moli H3PO3

H2SO3

M=2AH + AS + 3AO=2 + 32 + 3.16=82 -------> 82 g/moli
