Answer:
M KIO3 = 1.254 mol/L
Explanation:
∴ w KIO3 = 553 g
∴ mm KIO3 = 214.001 g/mol
∴ volumen sln = 2.10 L
⇒ mol KIO3 = (553 g)×(mol/210.001 g) = 2.633 mol
⇒ M KIO3 = (2.633 mol KIO3 / (2.10 L sln)
⇒ M KIO3 = 1.254 mol/L
Answer:
4.99 x 10⁻⁷ meters or 499 nanometers
Explanation:
Use the formula:
λ = c/ν, where λ = wavelength, c = the speed of light (it's constant, 2.998 x 10⁸ m/s), and ν = frequency
λ = (2.998 x 10⁸ m/s)/(6.01 x 10¹⁴ 1/s)
λ = 4.98835 x 10⁻⁷
Round to nearest hundreth and you get 4.99 x 10⁻⁷ meters, or 499 nanometers.
