What is the molar mass of a substance
Answers
Explanation:
An atom or object that occupies space also has mass. Molar mass or molecular weight is the mass of 1 mole of a substance.
The formula to calculate molar mass is as follows.
For example, molar mass of will be as follows
= ) g/mol
= (45.98 + 12.01 + 48.00) g/mol
= 105.99 g/mol
Therefore, it can be concluded that the sum of mass of all the atoms in grams make up 1 mole of a particular molecule. This mass is known as the molar mass or molecular weight.

Final answer:
Water helps in maintaining temperature in cells due to its high heat capacity. This property allows water to absorb or release a large amount of heat without significantly changing its own temperature. As such, cells can keep a stable temperature despite environmental changes.
Explanation:
Water has a high heat capacity, which is the amount of heat it takes to change its temperature. Due to this high heat capacity, it can absorb or release a large amount of heat without a significant change in its own temperature. This helps cells maintain a relatively stable temperature and protect biological processes. For instance, when the external environment is hot, cells can avoid getting overheated as the water in them absorbs and distributes the heat evenly. Similarly, if the environment is cold, the water in the cells releases heat which helps to keep them warm. Hence, regardless of the temperature changes in the environment, the high heat capacity of water aids cells in preserving a relatively even temperature.

The action that could slow a chemical reaction rate is adding more of a substance to a mixture. The answer is letter d. It does not give time for the rest of the reactants to be consumed because you are adding more of it causing to slow the reaction.
