How many moles of carbon monoxide (CO) is there in 840 o? Make sure to include the units and round to the nearest of

## Step 1<br />The molar mass of carbon monoxide (CO) is 28.01 g/mol. This is the weight of one mole of CO.<br /><br />## Step 2<br />To find the number of moles in 840 g of CO, we use the formula:<br />### **Number of moles = \(\frac{\text{Given mass}}{\text{Molar mass}}\)**<br /><br />## Step 3<br />Substitute the given values into the formula:<br />### **Number of moles = \(\frac{840 \text{ g}}{28.01 \text{ g/mol}}\)**<br /><br />## Step 4<br />Calculate the number of moles, which is approximately 30.00 moles.
