Determine the number of atoms in 51.0 grams of sodium, Na. (The mass of one mole of sodium is 22.99 g.)
miskamm [114]

Answer:

The answer is

<h3>1.340 × 10²⁴ sodium atoms</h3>

To find the number of atoms of sodium we use the formula

N = n × L

where

n is the number of moles

N is the number of entities

L is Avogadro's constant which is

6.02 \times  {10}^{23}

We need to find the number of moles first

The formula is

n =  \frac{m}{M}

where

M is the molar mass

m is the mass

n is the number of moles

From the question

M = 22.9 g/mol

m = 51.0 g

n =  \frac{51}{22.9}

n = 2.227 moles

So the number of sodium atoms is

N = 2.227 \times 6.02 \times  {10}^{23}

We have the final answer as

<h3>1.340 × 10²⁴ sodium atoms</h3>

Hope this helps you
