Question

calculate the molar mass of co₂. 14 g/mol 28 g/mol 44 g/mol 36 g/mol

Explanation:

Step1: Recall atomic masses

Carbon (C) has an atomic mass of approximately $12\ \text{g/mol}$, and oxygen (O) has an atomic mass of approximately $16\ \text{g/mol}$.

Step2: Analyze the formula \(CO_2\)

In \(CO_2\), there is 1 carbon atom and 2 oxygen atoms. So we calculate the molar mass as: \(1\times12 + 2\times16\).

Step3: Perform the calculation

First, calculate \(2\times16 = 32\). Then add the mass of carbon: \(12 + 32 = 44\). So the molar mass of \(CO_2\) is \(44\ \text{g/mol}\).

Answer:

The option with "44 g/mol" (the orange - colored option, assuming the orange option is labeled with 44 g/mol among the given choices). If we consider the options as presented (with the orange one being 44 g/mol), the answer is the option corresponding to 44 g/mol (e.g., if the options are labeled as A.14 g/mol, B.28 g/mol, C.44 g/mol, D.36 g/mol, then the answer is C. 44 g/mol).
