Question

Dimensional Analysis 10. A recommended dose of a medicine is 125 mg for a 175 lb person. What would be a correct dose for a 141.5 lb person? 11. Convert the following temperatures from Fahrenheit to Celsius: 108°F- 12. The boiling point of a substance is the temperature at which the liquid starts boiling and t temperatures below its boiling point most of the substance exists as a liquid evaporating. At temperatures higher than its boiling point the substance (all of it) exists as the gas. A (here we assume that the substance is kept in a closed container). The boiling point of diethyl ether iquid or as a gas at the room temperature of 71°F? Prove your answer with calculations is 34.6 C. Do you expect diethyl ether to exist as a Check your answers (some answers are given in one format only although you are supposed to give answers to many questions using both standard and scientific notations).

for 175 lb person dose recommended is 125 mg

for 1 lb person dose recommended will be =125/175 mg

for 145.5 lb person dose recommended will be =(125/175)*145.5= 103.92 mg = 104 mg

Ans(11)

to change fahrenheit in celcius we use formula T(celcius )= T(fahrenheit)-32/1.8

1 degrre fahrenheit= 1-32/1.8= -17.22 degree celcius

108 degree fahrenheit= 108-32/1.8= 42.22 degree celcius
