How many moles are in 22.5 grams of zinc?

Answer 1

For this you need the Atomic Mass of Zn. Then take the mass in grams and divide it by the atomic number (multiplied by one mole for units to cancel) to find number of moles. Zinc's atomic mass is 65.4 grams.

22.5 g Zn / (65.4 grams) = .344 moles Zn

Answer 2

You must first know the molar mass of zinc. It is 65.4 g/mol. Now you can calculate the number of moles:

22.5 g x (1 mol / 65.4 g) = 0.34 mol (the grams cancel each other out, leaving you with just moles)

Answer 3

The molar mass of Zn is 65.3800 g / mol. Simply multiply the mass of Zn by the reciprocal of the molar mass of Zn to find the moles.

Answer 4

The answer is obtained by dividing the stated number of grams by the gram atomic mass of zinc, 65.39. The answer = 3.140, to the justified number of significant digits

Answer 5

Zn = 65.41 g

392.4 g Zn * (1 mol Zn/65.41 g Zn) = 5.999

There are approximately 6 moles in 392.4 grams of zinc.

Answer 6

number of moles = weight divided by relative atomic mass

= 6.5 divided by 65

= 0.1 mol/dm cubed

Answer 7

it depends on if u r talking about body moles or ground moles if ground mole consider if it is African, Asian, or Russian

Answer 8

The atomic mass of zinc, Zn is 65.4.

Amount of Zn in 65g sample = 65/65.4 = 0.994mol

Answer 9

Zinc has atomic mass 65.4

1 mole of zinc has mass of 65.4g

Accordingly, 28.14 moles of zinc has mass 28.14 x 65.4 = 1840g

Answer 10

1.25 moles
