Question

calculate CaCO3 mole 5 gm​

Answer 1

Answer:

caco3 +5H2o

Explanation:

calcium carbonate if react with 5gm of h2o it gives calcium carbonate +5h2

Answer 2

Explanation:

molecular mass of CaCO3 =sum of all masses of it 's components

Ca=40u

O=16u

C=12u

molecular mass=40+12+3*16=40+12+48=100u

therefore

molar mass of CaCO3 is 100 g

100 g if CaCO3 contains 1mole

?---------------> 5 moles

=100*5/1=500 grams

therefore

5 moles of CaCO3 contains 500 grams
