The molar mass of calcium is 40.08, oxygen is 16.0, and hydrogen is 1.01. What is the mass of one mole of calcium hydroxide (Ca(OH)2)?



Answer :

[tex]Ca(OH)_2[/tex]

[tex]MM=Molar~mass[/tex]

[tex]MM_{Ca(OH)_2}=MM_{Ca}+2*(MM_O+MM_H)[/tex]

[tex]MM_{Ca(OH)_2}=40.08+2*(16.0+1.01)[/tex]

[tex]MM_{Ca(OH)_2}=40.08+2*(17.01)[/tex]

[tex]MM_{Ca(OH)_2}=40.08+34.02[/tex]

[tex]\boxed{\boxed{MM_{Ca(OH)_2}=74.1~g/mol}}[/tex]
