Answer: c. The specific heat of seawater

Explanation: Specific heat is defined as the amount of heat required to raise the temperature of unit mass of the substance by a given amount.

Concentration of ions is measured by noting the conductivity of the solution.As higher is the conductivity, higher is the concentration of ions.

Concentration of dissolved oxygen is measured by using iodometric titrations in which iodine is involved.

pH is measured by knowing the concentration of hydrogen ions.

1.For the reaction P4 O10(s) + 6H2O(l) → 4H3PO4(aq), what mass of P
Alex17521 [72]
P₄O₁₀ + 6H₂O → 4H₃PO₄
The equation shows us that the molar ratio of
P₄O₁₀ : 6H₂O = 1:6

We also know that one mole of a substance contains 6.02 x 10²³ particles. We can use this to calculate the moles of water.
moles(H₂O) = (5.51 x 10²³) / (6.02 x 10²³)
= 0.92 mole
That means moles of P₄O₁₀ = 0.92 / 6
= 0.15

Each mole of P₄O₁₀ contains 4 moles of P. 
moles(P) = 4 x 0.15 = 0.6 mol
Mr of P = 207 grams per mol
Mass of P = 207 x 0.6
= 124.2 grams
