How many molecules are in 34.61 grams of sulfur dioxide?
SSSSS [86.1K]

This problem is providing us with the mass of sulfur dioxide and the molecules contained are required. At the end, the result turns out to be 3.252x10²³ molecules, according to:

<h3>Avogadro's number:</h3>

In chemistry, we use the Avogadro's number in order to successfully perform mole-mass-particles calculations. Defined as 6.022x10²³, it provides the number of atoms, molecules and ions in one mole of the substance.

In this case, in order to obtain the result, one first calculates the moles in 34.61 grams of sulfur dioxide and then utilize the Avogadro's number to obtain the number of molecules as shown below:

34.61gSO_2*\frac{1molSO_2}{64.1gSO_2}*\frac{6.022x10^{23}molecules}{1molSO_2}  \\\\3.252x10^{23}molecules

Gnesinka [82]

Answer:

I would say water

Explanation:

The molecules that make up ice actually have more space between them than the molecules in liquid water do. Steam can flow around really easily making there be even more space for them.

sorry if this is wrong. I just did research and this is what I got.

How many atoms are there in 10.2 moles of Phosphorous?​
nikdorinn [45]

There are 2.06 x 10²⁴ atoms

<h3>Further explanation </h3>

The mole is the number of particles (atoms, molecules, ions)contained in a substance

1 mol = 6.02.10²³  particles

Moles can also be determined from the amount of substance mass and its molar mass

  • number of atoms :

\tt 10.2\times 6.02\times 106{23}=2.06\times 10^{24}
