What is the mass in grams
natka813 [3]

Answer:

the mass of one mole of an element, or Avogadro's number (6.02 x 1023) of atoms, is equal to its atomic mass in grams. In other words, 1 amu = 1 gram/mole. So if the mass of one hydrogen atom is 1 amu, the mass of one mole of hydrogen is 1 gram.

What is the wavelength of a light that has a frequency of 5.00x10 to the 12 power s negative 1 power
Lilit [14]

The wavelength of the light is 6.00 × 10^(-5) m.

The formula connecting frequency <em>f</em> and wavelength λ is

<em>f</em>λ = <em>c</em>

where <em>c</em> = the speed of light [2.998 × 10^8 m·s^(-1)]

We can rearrange the formula to get

λ = <em>c</em>/<em>f </em>

∴ λ = 2.998 × 10^10 m·s^(-1)/5.00 × 10^12 s^(-1) = 6.00 × 10^(-5) m = 60.0 µm

Why does increasing the number of trials increase confidence in the results of the experiment?
valkas [14]
<span>It rises confidence for the reason that the more times you conduct the similar experiment over and over should either demonstrate your hypothesis right and wrong and remove any random incidences that might touch your results. Meaning it permits to have a more accurate measure or conclusion.</span>
