Calculating energy needs for an off-grid system?

See Table A-1 for R and M for several substances. An ideal gas is an imaginary substance that obeys the relation Pv = RT. It is experimentally observed that ... PV/RT= nTot. 1 atm(22.4 L)/(.0821Latm/molK)293 = 0.931 moles total .931 - .65 ... [R]t = [R]0 − kt. Rate = k[R] ln[R]t = ln[R]0 − kt. [R]t = [R]0 e. −kt. p v = RT p: absolute pressure v: specific volume: =1/ρ ρ: density. R: Gas constant: its value depends on particular gas for air R=1715 ft lb/slug °R. T ... PV = NRT. Where “R” is the gas constant, 0.082 L atm mole-1 K-1. P = (N/V)RT. Page 2. There are many ways to write the ideal gas law. They are all equivalent ... The gas constant (R) is (atmospheres x liters)/ (moles x Kelvin). Temperature (T) is measured in Kelvin. What is the R in PV nRT? The R is the ... Assume that the lungs are at 1.00 atm pressure and at a body temperature of 40 oC. ! ∙ $%&. (Hint: V, P, and T are given. Use the equation PV = nRT where R = ... ... r for a period of t years is. FV = PV + INT = PV(1 + rt). We can also solve for the present value PV to obtain. PV = FV/(1 + rt). Examples. 1. For a 8.5% simple ... Answer and Explanation: 1 ... Here, P is the pressure of the gas, V is the volume of the gas, n is the number of moles of the gas, R is the universal gas constant ... Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, ... ... PV/RT. Then substitute this into the molar mass equation to get M = mRT/PV. Remember to use consistent units. For example, if you use the ideal gas constant R ...
