Answer: Moles of iron for the given amount is 17.90 moles.
Step-by-step explanation:
We are given 1 kg of iron and we need to find the moles of it. To calculate the moles, we use the following equation:
![\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}](https://img.qammunity.org/2020/formulas/chemistry/high-school/gwh5prgbdt4s2p8o8xquycz897bwt6lvw1.png)
Mass of iron given = 1kg = 1000 grams (Conversion Factor: 1 kg = 1000g)
Molar mass of iron = 55.85g/mol
Putting values in above equation, we get:
![\text{Moles of iron}=(1000g)/(55.85g/mol)\\\\\text{Moles of iron}=17.90mol](https://img.qammunity.org/2020/formulas/chemistry/middle-school/w4a79w6s4ctyycoemr0n2uxeefjrh4bjj9.png)
Hence, moles of iron for the given amount is 17.90 moles.
