What is the molarity of a 3.14 m solution of KCl dissolved in water, given that the solution has a density of 1.13 g/mL? If 8.77 g of KI are dissolved in enough water to make 4.75 L of solution, what is the molarity of the solution? What is the mass p...
Question: a) What is the relative wt. % of Ca in the sample? b) How much Ca (in mg ) does the sample contain? c) There is 53.4ppmSr in the sample. Convert 53.4ppm to wt%Sr. What is the Sr/Ca ratio in the sample by w...
To find the specific heat ratio (γ) of diatomic gases, we can follow these steps:1. Understand the Definition of Specific Heat Ratio (γ): The specific heat ratio (γ) is defined as the ratio of the specific heat of a gas a
Foraqueous solutions(solutions where water is the solvent) near room temperature, the difference between molar and molal solutions is negligible. This is because around room temperature, water has adensityof 1 kg/L. This means the "per L" of molarity is equal to the "per kg" of molality....
