How many grams of a 14.0% (w/w) sugar solution contain 62.5<br> of sugar?
Delicious77 [7]

Answer:

m_{solution}=446.4g

Explanation:

Hello,

In this case, by-mass percent is computed in terms of the mass of the solute and the mass of the solvent as shown below:

\% m=\frac{m_{solute}}{m_{solution}} *100\%

Thus, solving for the mass of the solution, we obtain:

\frac{x}{y} m_{solution}=\frac{m_{solute}}{\% m}*100\%\\ \\m_{solution}=\frac{62.5g}{14.0\%}*100\% \\\\m_{solution}=446.4g

Regards.

What happens when light is not spread out
Maru [420]

Answer:

Spreading out a wave over a larger area just causes the wave strength to weaken, but does not cause gaps to form. Therefore, if you look at photons as waves, spatial gaps never form in light as it travels through free space, no matter how dim it gets.Spreading out a wave over a larger area just causes the wave strength to weaken, but does not cause gaps to form.
