Answer:
Explanation:
The atomic mass of <em>nickel</em> is 58.963g/mol. Thus, one mole of nickel weighs "exactly" 58.693g.
How much nickel does every coin contain?
How many times 58.693g contains 1.25g?
That means that you need to have 47 coins of nickel to have one mole of nickel.
Gravity causes mass wasting.
Answer:
Q1: 2. Molarity.
Q2: 2.51 x 10⁻³.
Explanation:
<u><em>Q1:</em></u>
- The molarity is defined as the no. of moles of solute in one liter of solution.
- It is can be calculated from the relation: M = (no. of moles of solute)/(Volume in L of the solution).
<u><em>Q2:</em></u>
∵ pH = - log[H₃O⁺]
∴ 2.60 = - log[H₃O⁺]
log[H₃O⁺] = -2.6.
<em>∴ [H₃O⁺] = 2.51 x 10⁻³.</em>
