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

1. Compare How do<br> residual soil and transported<br> soil differ?
just olya [345]

<u>Residual soil and transported  soil differ by as follows:</u>

Residual soil stays over its parent rock and transported soil forms from particles from another place.

<u>Explanation:</u>

Soil forms from weathering of rock. When a rocks get weathered it creates small paiticles. That forms different kind of soil. Soil varies in texture, structure, colour, composition and in pH level. Each and every soil type produced from parent rock. Depending upon the character of parent rock soil type is determined like basalt the igneous rock forms black soil.

Residual soil stays over parent rock it does not get off by the activities of natural agents like air, water, wind and glacier. Transported soil comes from hilly area to flat topped ground by transportation through some transporting agents of nature. It is immature soil.
