Taking the mass of the atmosphere to be 5.7E15 metric tons, what mass of carbon must be burned in order to increase the average carbon dioxide level in the atmosphere by 150ppm by volume (in metric tons)? what equations do i use?
Calculate the concentration of SO2(ppm) that must be reached in polluted air (in ppm) if the dissolved gas is to produce a pH of 4.1 in raindrops without any oxidation of the gas. Hint: Sulfurous acid equilibria how would i do this. what equations would i use.?
Given: cp,ice = 2090 J/kg◦C cp,water = 4186 J/kg ·◦C cp,steam = 2010 J/kg ◦C Lf = 3.33 × 105 J/kg Lv = 2.26 × 106 J/kg How much energy is required to change a 37 g ice cube from ice at −10◦C to steam at 116◦C? Answer in u...

density of water=1.0*10^3 so, 26*3.9*23*(1.0*10^3)-3.5=2332196.5
a 3.5 kg rectangular air mattress is 2.73m long, 1.1m wide, and .124m thick. what mass can it support in water befor sinking? answer in units of kg. so do i do volume times density=mass? 3.5*2.73*1.1*.124=1.303302
a physics book has a height of 26cm, a width of 23cm, and a thickness of 3.9cm. what is the density of the physics book if it weighs 17N? the acceleration of gravity is 9.81m/s^2. answer in units of kg/m^3 i know density=mass/volume but it says to answer in units of kg/m^3... ...
