Question

How many molecules are there in 6.8 miles of carbon monoxide gas

Answer 1

`\large \boxed{4.1* 10^(24)}`

Step-by-step explanation:

There are 6.022 × 10²³ molecules in 1 mol of CO

`\text{No. of molecules} = \text{6.8 mol CO} * \frac{6.022* 10^(23) \text{ molecules CO}}{\text{1 mol CO}}\\\\= \mathbf{4.1* 10^(24)}\textbf{ molecules CO}\\\\\text{There are $\large \boxed{\mathbf{4.1* 10^(24)}\textbf{ molecules}}$ in 6.8 mol of CO}`
