<span>Answer:
Moles C10H16O = 24.6 g/ 153.23 g/mol = 0.161
Moles benzene = 98.5 g / 78.1121 g/mol = 1.26
Mole fraction benzene = 1.26 / 1.26 + 0.161 = 0.887
vapor pressure = 100 x 0.887 = 88.7 mm Hg</span>
<span>The answer is letter B. Melting is an endothermic change, because ice absorbs energy from its surroundings as it melts. The melting process absorbs heat energy that causes the ice to melt. Endothermic change is when it absorbs energy from its surrounding. The other choices are incorrect because exothermic change releases energy to its surrounding.</span>
Answer:
Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol.
Sometimes bacteria perform fermentation, converting carbohydrates into lactic acid...

The number of moles in 3.612 x 10²⁴ molecules of CaO is 6 moles.
<h3>
Number of moles in the molecules</h3>
The number of moles in 3.612 x 10²⁴ molecules of CaO is calculated as follows;
6.02 x 10²³ molecules = 1 mole
3.612 x 10²⁴ molecules = ?
= (3.612 x 10²⁴ ) / (6.02 x 10²³ )
= 6 moles
Thus, the number of moles in 3.612 x 10²⁴ molecules of CaO is 6 moles.
