Convert 1.71 × 1024 atoms of carbon to moles of carbon.

beks73 [17]

You need to use Avogadro's constant to convert from atoms of carbon to moles of carbon.

1.71*10^24 atoms C * (1 mole/6.022*10^23 atoms) = 2.84 moles of carbon

30 POINTS PLEASE HELP ASAP

lina2011 [118]

Hello!

We have the following data:

f (radiation frequency) = $3.0*10^{19}\:Hz$

v (speed of light) = $3.0*10^8\:m/s$

λ (wavelength) = ? (in m)

Let's find the wavelength, let's see:

$f = \dfrac{v}{\lambda}$

$3.0*10^{19} = \dfrac{3.0*10^8}{\lambda}$

$\lambda = \dfrac{3.0*10^8}{3.0*10^{19}}$

$\boxed{\boxed{\lambda = 1*10^{-11}\:m}}\Longleftarrow(wavelenght)\end{array}}\qquad\checkmark$

I Hope this helps, greetings ... DexteR! =)
