How many atoms of Na would be in 2.53 moles of Na

15.24× 10²³ atoms

Explanation:

Given data:

Number of atoms of sodium = ?

Number of moles = 2.53 mol

Solution:

The given problem will solve by using Avogadro number.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

2.53 mol × 6.022 × 10²³ atoms / 1mol

15.24× 10²³ atoms

Avogadro number:

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
