Answer:
Depends on what are you refering to
Explanation:
So depending on what you are looking for (your question is quite vauge)

within that compound, there are 2 atoms of Potassium and 1 atom of Carbonate. Within Carbonate there are 4 atoms (1 carbon and 3 oxygens)
so answers may be

I hope this helps.
Answer: Mass is both a property of a physical body and a measure of its resistance to acceleration (rate of change of velocity with respect to time) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies.
Explanation: This what I could come up with. Hope this helps !!
The definition in Volume is a the amount of space a substance or object occupies, or that is enclosed within a container, especially when great. For example "The sewer could not cope with the volume of rainwater" . You can say it in different ways, such as capacity, size, magnitude, mass, bulk, extent and more. I hope this helps :-).
Answer:
6.517.
Explanation:
- It is known that for pure water: [H₃O⁺] = [OH⁻], so water is neutral.
<em>Kw = [H₃O⁺][OH⁻] = 9.25 x 10⁻¹⁴.</em>
∵ [H₃O⁺] = [OH⁻].
∴ [H₃O⁺]² = 9.25 x 10⁻¹⁴.
∴ [H₃O⁺] = √(9.25 x 10⁻¹⁴) = 3.041 x 10⁻⁷ M.
∵ pH = - log[H₃O⁺]
<em>∴ pH</em> = - log(3.041 x 10⁻⁷) = <em>6.517.</em>
