A survey of 1000 men ages 20 to 30 found that their heights were normally distributed, with a mean of 65 inches and a standard deviation of 2.5 inches. How many men have a height that is between 60 inches and 70 inches?
C5H12 (l) + 8O2 (g) → 5CO2 (g) + 6 H2O (g)
1. Given 4.3 x 1024 atoms of oxygen (O), how many moles of carbon dioxide (CO2) are present? Answer with 2 sig figs.
What is the pressure of 3.5 miles of gas at 1.1 kilo pascals and 420 Kel
If pressure is expressed in atmospheres and volume is expressed in liters, PΔV has units of L atm (liters × atmospheres). Remember that 1 atm = 101,325 Pa, and that 1 L = 1 dm3. Use this information to determine the number of joules corresponding to 2 L atm.
