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{O}_{3}=0.235moles

GIVEN:

MASS=23.6g

TO FIND:

Number of moles and Molecular mass of CaC{O}_{3}

EXPLANATION:

Moles = Mass/Molecular Mass

Molar mass of Ca=40

Molar mass of C=12

Molar mass of {O}_{3}=3×16=48

Molecular mass of CaC{O}_{3}=40+12+48=100gram/mole

Moles=23.5/100

NUMBER OF MOLES=0.235mole

NUMBER OF MOLES OF CaC{O}_{3}=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
