Answer:
The concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
Explanation:
The H⁺ concentration of a solution is exponentially related to its pH value:
![\rm [H^{+}] = 10^{-pH}](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-pH%7D)
.
For lemon juice:
![\rm [H^{+}] = 10^{-2.0} = 0.01\; M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-2.0%7D%20%3D%200.01%5C%3B%20M)
.
For stomach acid:
![\rm [H^{+}] = 10^{-1.0} = 0.1\; M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-1.0%7D%20%3D%200.1%5C%3B%20M)
.
Thus, the concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
To answer this question, we'll need the molar masses of nickel and vanadium:
Molar mass of nickel: 58.693g/mol
Molar mass of vanadium: 50.941g/mol
These values represent the mass of one mole of the element. A mole is the weight of Avogadro's number of atoms of an element (6.02 x 10^23 atoms).
We are given 58.693g of nickel, which is equivalent to one mole of nickel. Therefore, you will get the same number of atoms from one mole of vanadium, or 50.941g of vanadium.
Gold is classified as a Solid
