A bottle of methanol is spilled in the 25°C lab, and it pools to form a 6 cm diameter circle. Assume that methanol evaporation occurs through a stagnant air layer of 3.5 mm. The diffusion coefficient of methanol in air is 0.164 cm2 /s. What is the mass flowrate (mg/min) of methanol evaporating?

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
