Find the Mass of 1 Mole Co(NH_2)_2

$C o {(N H_{2})}_{2}$

Step 1

To find the mass of $1$ mole of $C o {(N H_{2})}_{2}$ 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 $C o {(N H_{2})}_{2}$ $=$ $(mass of Co)$ + $2 (mass of N)$ + $4 (mass of H)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $C o {(N H_{2})}_{2}$ $=$ $(58.9300003)$ + $2 (14.01000022)$ + $4 (1.00999999)$

Step 3

Simplify the result.

Simplify each term.

Multiply $2$ by $14.01000022$ .

mass of $1$ mole of $C o {(N H_{2})}_{2} = 58.9300003 + 28.02000045 + 4 (1.00999999) g$

Multiply $4$ by $1.00999999$ .

mass of $1$ mole of $C o {(N H_{2})}_{2} = 58.9300003 + 28.02000045 + 4.03999996 g$

Simplify by adding numbers.

Add $58.9300003$ and $28.02000045$ .

mass of $1$ mole of $C o {(N H_{2})}_{2} = 86.95000076 + 4.03999996 g$

Add $86.95000076$ and $4.03999996$ .

mass of $1$ mole of $C o {(N H_{2})}_{2} = 90.99000072 g$
