How many grams of oxygen gas are contained in a 15 l sample at 1.02 atm and 28oc?

Explanation:

We can use the Ideal Gas Law to solve this problem

pV = nRT

Data:

p = 1.02 atm

V = 15 L

T = 28 °C

Calculations:

(a) Convert temperature to kelvins

T = (28 + 273.15) K =  301.15 K

(b) Calculate the number of moles

(c) Calculate the mass

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
