What is the mass in grams of a 8.4 mole sample of iron?

mass in grams of 8.4 mole of Fe = 469.098  grams

Explanation:

Iron is a metal substance. The molecular mass of Iron is 55.845 gram. This means 1 mole of Iron substance contains 55.845 grams.

The chemical formula of Iron is Fe.

Atomic mass of Iron = 55.845 g

Since, 1 mole of Iron is 55.845 g

8.4 mole is ?

cross multiply

mass in grams of 8.4 mole of Fe = 8.4 × 55.845/1

mass in grams of 8.4 mole of Fe = 8.4 × 55.845/1

mass in grams of 8.4 mole of Fe = 469.098  grams

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
