<span>(5.08 * 10^21) / (6.022 * 10^23) = 0.0084357 moles * 195.084 g/mol = 1.65 g Atomic mass of platinum = 195.084 g/mol Avogadro's number = 6.022 * 10^23 so here you go</span>
Answer:
gas
Explanation:
The gas molecules are far apart and as such, when heated they gain more kinetic energy thereby colliding with one another and with the wall of the container thereby exerting pressure and also they can be compressed by reducing the distance between between the molecules.
pH = 9.5
Explanation:
We know that the hydronium ion concentration is [H₃O⁺] = 3.16 × 10⁻⁹ M.
The formula for pH is:
pH = -lg[H₃O⁺]
We input the known values to find the pH:
pH = -lg[3.16 × 10⁻⁹]
pH = 9.5

Answer:
sodium + chlorine --> sodium chloride
The value of equilibrium constant is equal to the quotient of the products raised to its stoichiometric coefficient over the reaction's reactants raised to its respective stoichiometric coeff. The equation is Kc=[SO2][Cl2]/[SO2Cl2]= [1.3*10^-2][1.3*10^-2]/[2.2*10^-2-<span>1.3*10^-2]=0.0188. The final answer is Kc=0.0188.</span>
