<span>Answer: 8.90 x 10¹⁴ Hz
</span><span />

<span>Explanation:
</span><span />

<span>1) Frequency (f) and wavelength (λ) are inversely related.
</span><span />

<span>2) The equation is: f = c / λ, where c is the speed of light
</span><span />

<span>3) c = 3 x 10⁸ m/s in vacUum
</span><span />

<span>4) To make the calculations you need yo use the conversion between nanometers and meters:
</span><span />

<span>1 meter = 10⁹ nanometer


</span><span>5) Calculations:</span>
<span /><span>
f = 3 x 10⁸ m/s / 337.1 x 10⁻⁹ m = 8.90 x 10¹⁴ Hz
</span><span />

<span>Hz is hertz, the SI unit for frequency and it means cycles per second, that is number of waves per second.

Given: wavelength of Nitrogen laser (∧) = 337.1 nm = 337.1 X 10^-9 m

We know that, Energy of photon (E) = hc/∧ = hv
where, v = frequency of photon and c = speed of light = 3 X 10^8 m/s

Thus, v = c/∧ = (3 X 10^8)/ (337.1 X 10^-9) = 8.899 X 10^14 s-1.

Answer: F<span>requency of nitrogen laser = </span>8.899 X 10^14 s-1.

2.54 mL of ethanol to mol ethanol (Hint: the density of ethanol is 0.789<br> g/mL.)
Katarina [22]

0.04350179862

Explanation:

Make sure to check for sig figs though. Basically, you have 2.54 mL and you multiply that by the 0.789 g/mL and mL cancels out and you are left with 2.00406g. There are 46.06844 grams per mol of ethanol, so to cancel out grams we multiply by 1/46.06844. And then we are left with 0.04350179862 mol

100 POINTS! HELP ME IF YOU LOVE JESUS!
mr Goodwill [35]
I only got 50 points (which is not 100). :-)

Look at the graph. At 80 °C, about 38 g of solute is able to dissolve, and that’s for ever 100 g of water. That means that for every 150 grams of water, 57 grams of solute can dissolve (38/2 = 19 + 38 = 57 g) at 80 °C. Since 57 g is greater than 55 g, all for he sodium chloride should dissolve in 150 g of water at 80 °C - you can put all of that into a “mathematical explanation”.
