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

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
