Sagot :
Answer:
Mg(OH)2 = 58.321g/mol
H2CO3 = 62.026g/mol
C6H12O6 = 180.156g/mol
Explanation:
Para hallar la masa molecular debemos, primero, identificar las moles de cada átomo presentes en una mol de una molécula. Por ejemplo, para el hidróxido de magnesio:
Mg = 1mol
O = 2mol
H = 2mol
Ahora, debemos hacer la suma del peso molecular de todos estos átomos. Esto es:
Mg = 1mol * (24.305g/mol) = 24.305g/mol
O = 2mol * (16g/mol) = 32g/mol
H = 2mol* (1.008g/mol) = 2.016g/mol
El peso molecular del hidróxido de magnesio es:
24.305g/mol + 32g/mol + 2.016g/mol = 58.321g/mol
Ácido Carbónico:
H = 2mol * (1.008g/mol) = 2.016g/mol
C = 1mol * (12.01g/mol) = 12.01g/mol
O = 3mol * (16g/mol) = 48g/mol
Masa molar = 62.026g/mol
Glucosa:
C = 6mol * (12.01g/mol) = 72.06g/mol
H = 12mol * (1.008g/mol) = 12.096g/mol
O = 6mol * (16g/mol) = 96g/mol
Masa molar = 180.156g/mol
