Seawater contains 8.1×10−3 g Sr2+ per kilogram of water. What is the concentration of Sr2+ measured in ppm?

Answer : The concentration of Sr²⁺ in ppm is, 8.1 ppm

Explanation : Given,

Mass of solute (Sr²⁺) = 8.1 × 10⁻³ g

Mas of solution = 1 kg = 1000 g

Parts per million (ppm) : It is defined as the mass of a solute present in one million (10⁶) parts by the mass of the solution.

Formula used :

Now put all the given values in this formula, we get

Hence, the concentration of Sr²⁺ in ppm is, 8.1 ppm

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
