Question

An iron atom has a mass of ×9.2710−23g and a cooking pot has a mass of 0.500kg . Use this information to answer the questions below. Be sure your answers have the correct number of significant digits. What is the mass of 1 mole of iron atoms? g Round your answer to 3 significant digits.How many moles of iron atoms have a mass equal to the mass of a cooking pot? Round your answer to 3 significant digits.

Answer 1

The mass of 1 mole of iron atoms is 55.8 grams. The number of moles of iron atoms with a mass equal to the mass of a cooking pot is 8.96 moles.

Step-by-step explanation:

The molar mass of iron is 55.8 g/mol. Therefore, the mass of 1 mole of iron atoms is 55.8 grams.

To calculate the number of moles of iron atoms with a mass equal to the mass of a cooking pot, we need to convert the mass of the cooking pot to grams. The mass of the cooking pot is 0.500 kg, which is equal to 500 grams. Now we can divide the mass of the cooking pot by the molar mass of iron to find the number of moles. 500 g / 55.8 g/mol = 8.955 moles. Rounding to 3 significant digits, the number of moles is 8.96 moles.
