Find the Mass of 1 Mole 2.5moldeO_2

$2.5 mol d e O_{2}$

To find the mass of $1$ mole of $2.5 mol d e O_{2}$ 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 $2.5 mol d e O_{2}$ $=$ $(mass of U)$ + $(mass of N)$ + $(mass of I)$ + $(mass of T>mol)$ + $2 (mass of O)$

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $2.5 mol d e O_{2}$ $=$ $(238.02999877)$ + $(14.01000022)$ + $(126.90000152)$ + $(0)$ + $2 (16)$

Simplify the result.

Remove parentheses.

mass of $1$ mole of $2.5 mol d e O_{2} = 238.02999877 + 14.01000022 + 126.90000152 + 0 + 2 (16) g$

Multiply $2$ by $16$ .

mass of $1$ mole of $2.5 mol d e O_{2} = 238.02999877 + 14.01000022 + 126.90000152 + 0 + 32 g$

Add $238.02999877$ and $14.01000022$ .

mass of $1$ mole of $2.5 mol d e O_{2} = 252.039999 + 126.90000152 + 0 + 32 g$

Add $252.039999$ and $126.90000152$ .

mass of $1$ mole of $2.5 mol d e O_{2} = 378.94000053 + 0 + 32 g$

Add $378.94000053$ and $0$ .

mass of $1$ mole of $2.5 mol d e O_{2} = 378.94000053 + 32 g$

Add $378.94000053$ and $32$ .

mass of $1$ mole of $2.5 mol d e O_{2} = 410.94000053 g$
