Given that the molar mass of the Red 40 dye is equal to 496.42 g/mol, how many grams of Red 40 food dye were in the 0.235 L solution of drink mix

The mass of the red 40 dye in the 0.235 L solution is 5.21 g

Molar mass of red 40 dye = 496.42 g/mol

Molar volume = 22.4 L

Density of red 40 dye = 22.16 g/L

Density of red 40 dye = 22.16 g/L

Volume = 0.235 L

Mass of red 40 dye =?

Mass = Density × Volume

= 22.16 × 0.235

Mass of red 40 dye = 5.21 g

Therefore, the mass of the red 40 dye in the solution is 5.21 g

5.21 g

Explanation:

Density of Red 40 = molar mass/molar volume

since the molar volume = 22.4 L

Density of Red 40 = 496.42 g/mol/22.4 L

Density of 496.42 g/mol = 22.16 g/L

But;

density = mass/volume

volume of Red 40 = 0.235 L

mass = density * volume

mass = 22.16 g/L * 0.235 L

mass = 5.21 g
