Answer : The density of an object is 0.93 g/mL
Explanation : Given,
Mass of an object = 3.8 g
Initial volume = 4.5 mL
Final volume = 8.6 mL
First we have to calculate the volume of an object.
Volume of an object = Final volume - Initial volume
Volume of an object = 8.6 mL - 4.5 mL
Volume of an object = 4.1 mL
Now we have to calculate the density of an object.
Formula used:
Now putting all the given values in this formula, we get:
Therefore, the density of an object is 0.93 g/mL
The most difficult concept will be the concept of patient drug tolerance because there are many drugs that have different side effects for different patients. Therefore, it is necessary to understand the response of certain drugs to different patients. This will help avoid wrong drug combinations. This can cause side effects.
To learn more about this concept, you need to do your homework on these different drugs and the tolerance reactions you may experience, and attend some drug tolerance seminars, where the speaker will give you more ideas . And a further explanation of the concept.
Another topic in chemistry that is most tough to understand is moles. We can understand this concept by understanding the fact mole is an amount of a substance which may be atoms, molecules, ions, etc which have exactly 6.02214076 * 1023 'elementary entities' of the substance.

Answer: Electric charges are of two general types: positive and negative.
Hope this helps... Stay safe and have a great day.... :D
True, for example, hydrogen peroxide (liquid):
H₂O₂ + H₂O ⇄ H₃O⁺ + HO₂⁻
HO₂⁻ + H₂O ⇄ H₃O⁺ + O₂²⁻
(the resulting solution is weakly conducting)
