Asmoking room with an air volume of 500 mis ventilated at the rate of 1000 m/hr. when it opens at 7 o'clock in the morning, its air is pure and 50 smokers enter, each starting to smoke two cigarettes per hour. an individual cigarette emits, among other things, about 1.40 mg of formaldehyde, a toxin that converts to carbon dioxide at the rate of 0.40/hr. estimate the formaldehyde concentration at steady state. if the threshold for eye irritation is 0.06 mg/mº, how does the steady state concentration compare with this threshold? 2. skim milk is prepared by the removal of some of the fat from whole milk. this skim milk is found to contain 90.5% water, 3.5% protein, 5.1% carbohydrate, 0.1% fat and 0.8% ash. if the original milk contained 4.5% fat, calculate its composition assuming that fat only was removed to make the skim milk and that there are no losses in processing.
