A compound consists of 81.8% C and 18.2% H by mass. What is its empirical formula?​
nataly862011 [7]

Answer:

Empirical formula of 81.8 carbon and 18.2 hydrogen

Steps

  • Find the empirical formula of a compound that has 81.8% of Carbon (C), 18.2% of Hydrogen (H).
  • Divide by fractional component of each mole value: C=1.5354936431103, H=4.0709872862205Round to closest whole numbers: C=2, H=4
<h3> Combine to get the empirical formula: C2H4</h3>

De Broglie's wave equation describes that particles have wave properties. The equation is 
    λ = h/mv

Where λ  is the wave length of the particle (m), h is the Planck's constant (6.62607 x 10⁻³⁴J s), m is the mass of a particle (kg) and v is the velocity (m/s).

λ = ?
h =  6.62607 x 10⁻³⁴<span> J s
m =200 g = 0.2 kg
v = 20 m/s

</span>By substitution,
    λ  = 6.62607 x 10⁻³⁴ J s / (0.2 kg x 20 m/s)
    λ  = 1.66 x 10⁻³⁴ m

Hence, the wavelength of the 200 g ball 1.66 x 10⁻³⁴ m.
