Question

What is the mass of 1 mol of iron (atomic mass 55.845 u)?

224 g
55.845 g
6.02 x 1023 g
127 g

Answer 1

it is 56 approximately

Step-by-step explanation:

the law is mass/molar mass = no. of moles

you have one mole of iron and the molar mass is 56 approximately

then the equation is

mass/56= 1

then this will be 56 grams

Answer 2

The mass of 1 mole of iron (atomic mass 55.845 u) is 55.8 g.

Step-by-step explanation:

The mass of 1 mole of iron (atomic mass 55.845 u) is 55.8 g. This can be obtained by referring to the periodic table, where the molar mass of iron is given as 55.8 g/mol. So, 1 mole of iron will have a mass of 55.8 grams.
