Question

C₆H₁₂O₆; Ca₃(PO₄)₂ e Ca(OH)₂, respectivamente: a) 180, 310 e 74.
b) 150, 340 e 73.
c) 180, 150 e 74.
d) 200, 214 e 58.
e) 321, 121, 80. ​

Answer 1

Resposta:a) 180, 310 e 74.

Explicação:

C6H12O6--->12.6+1.12+16.6--->72+12+96--->180 g/mol

Ca3(PO4)2--->40.3+31.2+16.8--->120+62+128--->310 g/mol

Ca(OH)2--->40.1+16.2+1.2--->40+32+2--->74 g/mol
