The  moles  of  CaCO3  which  are  there  in  antacid  tablet  that  contain  0.515g  CaCO3  is  calculated  as  follows

moles  =mass/molar  mass

the  molar  mass  of  CaCO3 =  ( 40  x1)+  (12  x  1)  + (16 x  3)=  100  g/mol

moles  is  therefore=  0.515g/100 g/mol=  5.15  x10^-3  moles

Answer:

0.00515molCaCO3

Explanation:

Hello,

By following the down below simple mass-mole relationship, the requested moles are computed, considering that the calcium carbonate has a molecular mass of 100g/mol:

M_{CaCO3}=40+12+16*3=100g/mol\\\\n_{CaCO3}=0.515gCaCO3*\frac{1molCaCO3}{100gCaCO3}=0.00515molCaCO3

Best regards.

What is the chemical equation for boiling a egg?
Nostrana [21]
Because an egg is an entire biological structure, made up of a mixture of chemicals rather than a single pure chemical compound, there is no one chemical formula to describe it. However, the basic structure and chemistry of an egg is highly conserved and varies little from species to species.
