QuestionWhat is the mass in grams of a 67.20 mol sample of iron? Provide your answer to 4 significant figures.

Studdy Solution

STEP 1

Assumptions1. The number of moles of iron is67.20 mol. The molar mass of iron (Fe) is55.845 g/mol

STEP 2

We can find the mass of the iron sample by using the formula $Mass = Number\, of\, moles \\times Molar\, mass$

STEP 3

Now, plug in the given values for the number of moles and the molar mass of iron to calculate the mass.
$Mass =67.20\, mol \\times55.845\, g/mol$

STEP 4

Calculate the mass of the iron sample.
$Mass =67.20\, mol \\times55.845\, g/mol =3752.184\, g$

STEP 5

Round the calculated mass to4 significant figures.
$Mass =3752\, g$ The mass of the67.20 mol sample of iron is3752 g.
