Question

Как определить число атомов цинка в образе массой 96 граммов?

Answer 1

MZn=96g
N-?
решение
MZn=65g/mol
n=m/M=96g/65g/mol=1.5mol
N=n*Na=1.5*6*10(23)=9*10(23) атомов

Answer 2

Determining the Number of Zinc Atoms in a Sample Mass of 96 Grams

To determine the number of zinc atoms in a sample mass of 96 grams, we can use the formula:

Number of atoms = (Mass of sample / Atomic mass of element) * Avogadro's number

Where: - Mass of sample = 96 grams - Atomic mass of zinc (Zn) = 65.38 grams/mol (rounded to two decimal places) - Avogadro's number = 6.022 x 10^23 atoms/mol

Using the formula, we can calculate the number of zinc atoms in the given sample mass.

Number of atoms = (96 grams / 65.38 grams/mol) * 6.022 x 10^23 atoms/mol

Now, let's calculate the number of zinc atoms.
