$?=\frac{\text { mass of water vapor (grams) }}{\text { mass of dry air (kilograms) }}$The formula shown above defines the humidity measure known as:
A) the mixing ratio.
B) relative humidity.
C) vapor pressure.
D) absolute humidity.

Question

Quizplus · Accepted Answer

The mixing ratio is a measure of the mass of water vapor in the air compared to the mass of the dry air, typically expressed in grams of water vapor per kilogram of dry air.

?= mass of water vapor (grams) mass of dry air (kilograms) ?=\frac{\text { mass of water vapor (grams) }}{\text { mass of dry air (kilograms) }}?= mass of dry air (kilograms) mass of water vapor (grams) ​

$?=\frac{\text { mass of water vapor (grams) }}{\text { mass of dry air (kilograms) }}$
