CORRECT QUESTION:
Calcite is a mineral composed of calcium carbonate, CaCO3. A sample of calcite composed of pure calcium carbonate weighs 23.6g. How many moles of calcium carbonate is this?
ANSWER:
NUMBER OF MOLES OF CaC=0.235moles
GIVEN:
MASS=23.6g
TO FIND:
Number of moles and Molecular mass of CaC
EXPLANATION:
Moles = Mass/Molecular Mass
Molar mass of Ca=40
Molar mass of C=12
Molar mass of =3×16=48
Molecular mass of CaC=40+12+48=100gram/mole
Moles=23.5/100
NUMBER OF MOLES=0.235mole
NUMBER OF MOLES OF CaC=0.235moles

Answer:
100.09 g / mol
Explanation:
1 Ca 1 (40.08) = 40.08
1 C 1 (12.01) = 12.01
3 O 3 (16.00) =48.00
=100.09
I hope this might help you
