When carbon dioxide is passed over red hot carbon, carbon monoxide is produced according to the equation:
`CO_(2)+Cto2CO`
What volume of carbon monoxide at S.T.P. can be obtained from 3 g of carbon ? (The molar volume of a gas is 22.4 litres)

Explanation

To solve the problem of how much volume of carbon monoxide (CO) can be produced from 3 grams of carbon (C) when carbon dioxide (CO₂) is passed over red hot carbon, we can follow these steps:

### Step 1: Write the balanced chemical equation
The reaction between carbon dioxide and carbon can be represented by the following balanced equation:
\[ \text{CO}_2 + \text{C} \rightarrow 2 \text{CO} \]

### Step 2: Determine the molar mass of carbon
The molar mass of carbon (C) is 12 g/mol.
