On a unusually warm day in February, Monica ( a burger flipper by default) is sweating profusely over a hot grill. The temperature in the fast food kitchen is 108degF or 42.2deg C and the relative humidity is 88%. During her one morning break, she takes a drink of some ice cold distilled water from a plastic cup. Before Monica takes a drink, she drips 6 drops of sweat into the cup. Given: the concentration of sodium in her sweat is 24 mmol/L, the concentration of potassium in sweat is 7.5 mmol/L, the pH of her the sweat is 6.0, her sweat production rate is 2.1 L/hr, a drop of sweat is 0.1 mL, the concentration of sodium in the plastic cup after her sweat is added is 0.25mg/L, and that Monica would rather be studying physiology than "sweating her brains out". How much fluid is in the plastic cup before she takes a 30 mL sip?
