Consider the compound sn(co3)2 and answer the following questions:

a. what is the name of this compound?
b. what is the molar mass of this compound? explain how you calculated this value.

A.) Name of Sn(CO)3 is Tin(lV)Carbonate.

'IV' indicates the oxidation number of Sn.

B.) Molar mass of compound = summation [number of atoms in compound x atomic number of that element].

Therefore molar mass of Sn(CO3)2, 
              
= at.weight of Sn + 2 x at.weight of C + 6 x at.weight of O
=    118.71 + 2 x 12.01 + 6 x 15.999
=            238.67 amu.

Hence molar mass of Sn(CO3)2 is 238.67 amu.

Hope this helps!

 

Ithinks its false. tell me if im wrong

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this
