What is the concentration (M) of CH3OH in a solution prepared by dissolving 12.5 g of CH3OH in sufficient water to give exactly
timurjin [86]

Answer:

1.7 M

Explanation:

Concentration is the number of moles of solute dissolved in 1 L of solution

Concentration = number of moles of solute / volume of solution

Number of moles of solute needs to be calculated first

Mass of methanol - 12.5 g

Molar mass of methanol - 32 g/mol

Number of methanol moles - 12.5 g / 32 g/mol = 0.39 mol

Therefore concentration is = 0.39 mol / 0.230 L = 1.7 mol/L

Concentration is 1.7 M

13. What is the photon energy associated with visible light with a wavelength of 4.25x10^-7 m?
4vir4ik [10]

\\ \sf\bull\longmapsto E=hv

\\ \sf\bull\longmapsto E=\dfrac{hc}{\lambda}

\\ \sf\bull\longmapsto E=\dfrac{6.626\times 10^{-34}Js\times 3\times 10^8ms^{-1}}{4.25\times 10^{-7}m}

\\ \sf\bull\longmapsto E=\dfrac{19.878\times 10^{-26}Jm}{4.25\times 10^{-7}m}

\\ \sf\bull\longmapsto E=4.677\times 10^{-19}J

\\ \sf\bull\longmapsto E=4677\times 10^{-16}J

\\ \sf\bull\longmapsto E=4677eV
