Question

calculate the number of molecules present in 0.75 moles of CO₂

Answer 1

Answer:

answer is

Explanation:

0.75moles in co2=6.022*10^23

=0.75*6.022*10^23

=4.5165*10^23 each molecule present in co2 molecule.

Answer 2

Answer:

In 0.75 moles of $CO_{2}$ we have $4.52\times10^{23}$ molecules.

Explanation:

We know that one mole of any substance will be containing $6.02\times 10^{23}$atoms, molecules, particles, or ions.  

We have 0.75 moles of $CO_{2}$ and to calculate the number of molecules in it, we have to follow the steps below-

1 mole of $CO_{2}$ = $6.02\times 10^{23}$ molecules of $CO_{2}$

0.75 moles of $CO_{2}$ = $x$ molecules of $CO_{2}$

($6.02\times 10^{23}$) × 0.75 = $x$

$4.52\times 10^{23} = x$

$4.52\times10^{23}$ molecules of $CO_{2}$ are present in 0.75 moles.
