Question

1. how many grams are in 4.77 mol of iron?

Explanation:

Step1: Recall molar - mass of iron

The molar mass of iron (Fe) is approximately 55.85 g/mol.

Step2: Use the formula to convert moles to grams

The formula is $m = n\times M$, where $m$ is mass, $n$ is the number of moles, and $M$ is the molar mass. Here, $n = 4.77$ mol and $M=55.85$ g/mol. So, $m=4.77\times55.85$.
$m = 4.77\times55.85=266.3045$ g

Answer:

266.30 g (rounded to two decimal places)
