Answer: 126g

Step-by-step explanation:

No of moles = mass given/molar mass

No of moles given=2.25mol

Molar mass of Fe= 56

Mass =?

Substitute the values into the formula

No of moles = mass given/molar mass

2.25= mass/56

Mass= 56×2.25

Mass = 126g

Mass of Fe in 2.25mols is 126g

Answer:

126g

Step-by-step explanation:

Data obtained from the question include:

Mole of Fe = 2.5moles

Molar Mass of Fe = 56g/mol

Mass of Fe =?

Number of mole = Mass/Molar Mass

Mass = number of mole x molar Mass

Mass of Fe = 2.25 x 56

Mass of Fe = 126g

Therefore, the mass in 2.25mol of Fe is 126g
