In order to determine the number of molecules of nitrogen dioxide that are in 1.28 g of nitrogen dioxide, we first need to know these values:

Molar mass of nitrogen dioxide = 46.0055 g/mol
Avogadro's number = 6.022 x 10^23 molecules/mol

Then, we divide 1.28 g by the molar mass and multiply the resulting value to Avogadro's number:

1.28 g/ 46.0055 g/mol x 6.022 x 10^23 molecules/mol = 1.6755 x 10^22 molecules of nitrogen dioxide

Hello! 

How many molecules of nitrogen dioxide are in 1.28 g of nitrogen dioxide?

Let's first find the molecular mass of nitrogen dioxide, knowing that by Avogadro's Law for each mole of a substance we have 6.02 * 10²³ molecules.

N = 1*14 = 14 amu

O = 2*16 = 32 amu

---------------------------

molecular mass of nitrogen dioxide = 14 + 32 = 46 g/mol

How many molecules of nitrogen dioxide are in 1.28 g of nitrogen dioxide NO2?

46 g ---------------- 6.02*10²³ molecules

1.28 g -------------  y molecules

46*y = 1.28*6.02*10^{23}

46y = 7.7056*10^{23}

y = \dfrac{7.7056}{46}*10^{23}

y = 0.167513043*10^{23}

\boxed{\boxed{y \approx 1.675*10^{22}\:molecules\:of\:nitrogen\:dioxide}}\end{array}}\qquad\checkmark

Why do you think different liquids have different freezing points
Ganezh [65]
I think that different liquids have different freezing points because every liquid consists of different atoms and different things that make up the atom causing them to have different freezing points.
