What is the concentration of the murexide soution with a transmittance of 28.65%. (molar absorptivity = 3847)
Ainat [17]

Answer:

The concentration of the murexide solution is 0.0000745 M

Explanation:

From Beer-Lambert's law,

A = εlc

A = Absorbance = 28.65% = 0.2865

ε = molar absorptivity = 3847 M/cm

l = path length = 1cm

c = concentration in mol/L = ?

c = A/εl = 0.2865/(3847×1) = 0.0000745 mol/L

Hope this Helps!

A fish tank holds 31 gal of water. How many kilograms of water are in the fish tank?
Oksanka [162]

Answer:

3.785411784

Explanation:1 gallon (gal) = 3.785411784 kilogram (kg). Gallon (gal) is a unit of Volume used in Standard system. Kilogram (kg) is a unit of Weight used in Metric system. Please note this is volume to weight conversion, this conversion is valid only for pure water at temperature 4 °C.

US oz = 28.349523125 g

US fl oz = 29.5735295625 ml (milliliters) = 29.5735295625 g (grams) of pure water at temperature 4 °C.

US cup = 8 fl oz = 236.5882365 ml (milliliters) = 236.5882365 g (grams) of pure water at temperature 4 °C.

The US gallon is equal to 3.785411784 liters and defined as 231 cubic inches. Kilograms also can be marked as kilogrammes in UK.
