☃️ Chemical formulae ➝ [tex]\sf{Al_2(CO_3)_3}[/tex]
For solving this question, We need to know how to find moles of solution or any substance if a certain weight is given.
[tex] \boxed{ \sf{no. \: of \: moles = \frac{given \: weight}{molecular \: weight} }}[/tex]
❍ Molecular weight of [tex]\sf{Al_2(CO_3)_3}[/tex]
= 2 × 27 + 3 × 12 + 9 × 16
= 54 + 36 + 144
= 234
❍ Given weight: 10 g
Then, no. of moles,
⇛ No. of moles = 10 / 234
⇛ No. of moles = 0.0427 moles
⚘ No. of moles of Aluminium carbonate in the given weight = 0.0427 moles.
