Find the Mass of 1 Mole Ca(OH)_2

$C a {(O H)}_{2}$

Step 1

To find the mass of $1$ mole of $C a {(O H)}_{2}$ look up the atomic mass of each element and multiply it by the number of atoms contained in each element in the molecule.

mass of $1$ mole of $C a {(O H)}_{2}$ $=$ $(mass of Ca)$ + $2 (mass of O)$ + $2 (mass of H)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $C a {(O H)}_{2}$ $=$ $(40.08000183)$ + $2 (16)$ + $2 (1.00999999)$

Step 3

Simplify the result.

Simplify each term.

Multiply $2$ by $16$ .

mass of $1$ mole of $C a {(O H)}_{2} = 40.08000183 + 32 + 2 (1.00999999) g$

Multiply $2$ by $1.00999999$ .

mass of $1$ mole of $C a {(O H)}_{2} = 40.08000183 + 32 + 2.01999998 g$

Simplify by adding numbers.

Add $40.08000183$ and $32$ .

mass of $1$ mole of $C a {(O H)}_{2} = 72.08000183 + 2.01999998 g$

Add $72.08000183$ and $2.01999998$ .

mass of $1$ mole of $C a {(O H)}_{2} = 74.10000181 g$
