Determine the number of moles in 154g of Li2CO3
mezya [45]

<em><u>Given:</u></em>

Weight of Li2CO3 = 154 g

<em><u>To find:</u></em>

number of moles of Lithium Carbonate Li2CO3 = ?

<em><u>Solution:</u></em>

first we have to calculate the molar mass of Lithium Carbonate,

The elemental composition of Li2CO3

Li = 2 units, Atomic weight of each Li atom is 7 g/mol

Li = 2 × 7 = 14 g/mol

C = 1 unit, Atomic weight of Carbon is 12 g/mol

O = 3 units, Atomic weight of each O atom is 16 g/mol

O = 3 × 16 = 48 g/mol

Atomic weight of Li2CO3 = 14+12+48 = 72 g/mol

now,

number  \: of  \: moles = \:  \frac{Given  \: weight  \: of \:  substance}{Atomic \:  weight \:  of  \: substance}

Number of moles = 154/72 = 2.14 moles

<u>Answer- The number of moles of Lithium Carbonate is 2.14 </u>
