Chandra wants to know how many moles are contained in 150.0 g ccl4 (carbon tetrachloride). what quantity of ccl4 should she use to make this conversion? number of moles molecular mass molar mass mole ratio

Chandra will use the conversion of 'number of moles'.There are 0.9751 moles of carbon tetra chloride.

Explanation:

Mass of the Carbon tetra chloride = 150.0 g

Molar Mass of the carbon tetra chloride = 153.82 g/mol

Number of moles:

There are 0.9751 moles of carbon tetra chloride in 150 grams of carbon tetra chloride. Chandra will use the conversion of 'number of moles'.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
