Question

Calculate the number of moles equivalent 10.0 gram of aluminium carbonate ​

Answer 1

ok it’s gonna be the c= 12

Answer 2

`\LARGE{ \boxed{ \red{ \rm{Answer}}}}`

☃️ Chemical formulae ➝
`\sf{Al_2(CO_3)_3}`

How to find?

For solving this question, We need to know how to find moles of solution or any substance if a certain weight is given.

`\boxed{ \sf{no. \: of \: moles = (given \: weight)/(molecular \: weight) }}`

Solution:

❍ Molecular weight of
`\sf{Al_2(CO_3)_3}`

= 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.
