The molar mass of C₇H₁₆ and the molar mass of CaCO₃ contain approximately the same number of grams.
Explanation:
C₇H₁₆ is an alkane. C₇H₁₆ doesn't have cations or anions. But CaCO₃ is an ionic compound which has Ca²⁺ as the cation and CO₃²⁻ as the anion. But both compounds have approximately same molar mass.
Molar mass of CaCO₃ = 100.09 g/mol
Molar mass of C₇H₁₆ = 100.21 g/mol
