Determine the mass of 2.4 x 10^24 atoms of gold?​
Scorpion4ik [409]

Answer:

Mass = 785.9 g

Explanation:

Given data:

Atoms of gold = 2.4 × 10²⁴ atoms

Mass of gold = ?

Solution:

First of all we will convert the number of atoms into moles.

2.4 × 10²⁴ atoms × 1 mol/ 6.02 × 10²³ atoms

number of moles = 3.99 mol

Now we will determine the mass of gold.

Mass = number of moles × molar mass

Mass =  3.99 mol × 196.97 g/mol

Mass = 785.9 g
