Ayudaaaaaaaaaaaaaaaaa

es para un tarea, sin bromas por favor

Answer 1

Respuesta:

Mm H2SO4 : 98 g/mol

Mm CaCO3 : 100 g/mol

Mm SO2 : 64 g/mol

Mm Ca3(PO4)2 : 310 g/mol

Mm H3PO4: 98 g/mol

Explicación:

H2SO4

H: 2  x 1 = 2 g/mol

S: 1 x 32 = 32 g/mol

O: 4 x 16 = 64 g/mol

Mm H2SO4: 98 g/mol

CaCO3

Ca: 1  x 40 = 40 g/mol

C: 1 x 12 = 312 g/mol

O: 3 x 16 = 48 g/mol

Mm CaCO3: 100 g/mol

SO2

S: 1 x 32 = 32 g/mol

O: 2 x 16 = 32 g/mol

Mm SO2: 64 g/mol

Ca3(PO4)2

Ca: 3  x 40 = 120 g/mol

P: 2 x 31 = 62 g/mol

O: 8 x 16 = 128 g/mol

Mm Ca3(PO4)2: 310 g/mol

H3PO4

H: 3  x 1 = 3 g/mol

P: 1 x 31 = 31 g/mol

O: 4 x 16 = 64 g/mol

Mm H3PO4 = 98 g/mol

HCl

H: 1  x 1 = 1 g/mol

Cl: 1 x 35,5 = 35,5 g/mol

Mm HCl = 36.5 g/mol

Ca(NO3)2

Ca: 1  x 40 = 40 g/mol

N: 2 x 14 = 28 g/mol

O: 6 x 16 = 96 g/mol

Mm Ca(NO3)2: 164 g/mol

H2S

S: 1 x 32 = 32 g/mol

H: 2 x 1 = 2 g/mol

Mm H2S: 34 g/mol
