What is the de broglie wavelength of a red blood cell, with mass 1.00 x 10-11 g, that is moving with a speed of 0.400 cm/s?

We have a formula for finding the de Broglie wavelength. The formula is written below:

λ = h/mv
where
h is the Planck's constant = 6.626×10⁻³⁴ J·s
m is the mass
v is the velocity

Substituting the values,
λ = 6.626×10⁻³⁴ J·s/(1.00 x 10-11 g)(1 kg/1000 g)*(0.400 cm/s)(1 m/100 cm)
λ = 1.66×10⁻¹⁷ m
