Calculate the mass of 0.5 moles of caco3 in grams​

Explanation:

Solution— Molecular mass of CaCO3= 40+12+3×16 = 100 No. mole of CaCO3 = 50g/100g = 0.5 0.5 mole of CaCO3 contains 1.5 moles of oxygen atoms No. of oxygen atoms = 1.5 × 6.022×1023 = 9.033×1023 atoms Mass of Oxygen atoms = 1.5 × 16 = 24 g.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
