To find out how many moles of cobalt are in 27.4 grams of cobalt, follow these steps:
1. Identify the given data:
- Mass of cobalt: 27.4 grams
- Molar mass of cobalt: 58.93 grams per mole
2. Use the formula to convert grams to moles:
[tex]\[
\text{Number of moles} = \frac{\text{Mass (in grams)}}{\text{Molar mass (in grams per mole)}}
\][/tex]
3. Plug in the given values:
[tex]\[
\text{Number of moles} = \frac{27.4 \text{ grams}}{58.93 \text{ grams per mole}}
\][/tex]
4. Perform the division to find the number of moles:
[tex]\[
\text{Number of moles} \approx 0.465 \text{ moles}
\][/tex]
Therefore, there are approximately 0.465 moles of cobalt in 27.4 grams of cobalt.
