WebApr 14, 2024 · Blood volume refers to the total amount of fluid circulating within the arteries, capillaries, veins, venules, and chambers of the heart at any time. The components that add volume to blood include red blood cells (erythrocytes), white blood cells (leukocytes), platelets, and plasma. Plasma accounts for about 60% of total blood volume, while …
WebThe Ideal Gas Law. The ideal gas law relates the variables of pressure, volume, temperature, and number of moles of gas within a closed system. The ideal gas law takes the form: PV = nRT. P = Pressure of the confined gas in atmospheres. V = Volume of the confined gas, in liters. n = Number of moles of gas. R = Gas Constant, 0.0821 L·atm/mol·K. WebFeb 14, 2024 · R = 0.08206 L.atm/K.mol (commonly used with PV = nRT to find the number of moles) R = 8.314 J/K.mol (commonly used with w = -nRTln (V2/V1)) so it all depends on what you are trying to solve for and what units will cancel with either R value to get the actual units you need. Top.
WebNov 19, 2024 · There are a couple of common equations for writing the combined gas law. The classic law relates Boyle's law and Charles' law to state: PV/T = k. where P = pressure, V = volume, T = absolute temperature (Kelvin), and k = constant. The constant k is a true constant if the number of moles of the gas doesn't change. Otherwise, it varies.
WebMar 9, 2024 · Temperature of the gas, T = 30 °C = 303 K. Ideal gas constant, R = 0.0821 L atm/mol K. Using the formula of ideal gas law, P V = n R T. 2 × 4 = n × 0.0821 × 303. 8 = n × 24.8763. n = 0.32 mol. Therefore, the number of moles of the gas is 0.32 mol.
