Question

1. what is the mass of 2.0 moles of carbon (c)?

Explanation:

Step 1: Recall the molar mass of carbon

The molar mass of carbon (C) is approximately \(12\space g/mol\) (from the periodic table, the atomic mass of carbon is about 12 atomic mass units, and molar mass in grams per mole is numerically equal to atomic mass in atomic mass units).

Step 2: Use the formula \(mass = moles\times molar\space mass\)

We know the number of moles (\(n = 2.0\space mol\)) and the molar mass of carbon (\(M = 12\space g/mol\)). Plugging these values into the formula:
\(mass = n\times M = 2.0\space mol\times12\space g/mol\)

Step 3: Calculate the mass

\(2.0\space mol\times12\space g/mol = 24\space g\)

Answer:

The mass of 2.0 moles of carbon is \(24\space g\).
