How many molecules are in 1.52 mol of dinitrogen monoxide

9.15 × 10²³ molecules of N₂O present.

Explanation:

Given data:

number of moles = 1.52 mol

molar mass of N₂O = 44.013 g/mol

number of molecules = ?

Solution:

First of all we will calculate the mass of 1.52 mol.

mass = number of moles × molar mass

mass = 1.52 × 44.013 g/mol

mass = 66.9 g

Now we will find the number of molecules by using Avogadro number,

The number 6.022×10∧23 is called Avogadro number and it is the number of atoms or molecule in one gram atom of an element or one gram molecule of a compound.

44.013 g of N₂O = one mole of N₂O= 6.02 × 10²³ molecules

For 66.9 g:

66.9 g/ 44.013 g × 6.02 × 10²³ molecules

9.15 × 10²³ molecules of N₂O present

a is the answer

explanation:

which statement about trans-fatty acids is false?

a. the conversion of cis-fatty acids to trans-fatty acids is inhibited by the presence of antioxidants.
