(a)
Interpretation:
The units of 70.5 and 8.27×10-7 should be calculated.
Concept introduction:
The density of a fluid is given by the empirical equation,
It is assumed that the given equation is valid and therefore dimensionally homogeneous. So, the dimension of the left hand side and right hand side of the equation is equal.
(b)
Interpretation:
The density for a pressure of 9.00×106 N/m2 should be calculated.
Concept introduction:
The density of a fluid is given by the empirical equation,
(c)
Interpretation:
A formula for ρ (g/cm3) as a function of P (N/m2) should be derived.
Concept introduction:
The density of a fluid is given by the empirical equation,

- 12. (c) Potassium metal reacts with water. 2K(s) + 2H,0(1) → 2KOH(aq) + H,(g) 0.2346g of potassium is reacted with excess water. Calculate the volume of gas formed. The gas volume is measured in cm° at room temperature and pressure. answer =arrow_forwardThe density of mercury changes approximately linearly with temperature as p=851.5-0.086T in Ibm/ft^3 (T in degrees F), so the same pressure difference will result in a manometer reading that is influenced by temperature. If a pressure difference of 14.7 Ibf/in^2 is measured in the summer at 95F and in the winter at 5F, what is the difference in column height between the two measurements? 273.488 in O 1.899 ft O 273.488 ft O 8.493 ftarrow_forwardNitrogen gas in a cylinder has a pressure of 1.85x10^3 psi. What is the gas density at 25 Celsius in g/L units 1atm = 14.7 psi arrow_forward
- Given the equation V=√3RT/M,. What is the unit of v if R is in erg/mol•K, M is in g/mol and erg=g•cm²/s²?arrow_forwardWhat Celsius temperature, T2T2T_2, is required to change the volume of the gas sample in Part A (T1T1T_1 = 15 ∘C∘C , V1V1V_1= 1.70×103 L ) to a volume of 3.40×103 L? Assume no change in pressure or the amount of gas in the balloon. Express your answer with the appropriate units. A sample of gas in a balloon has an initial temperature of 15 ∘C and a volume of 1.70×103 L . If the temperature changes to 91 ∘C , and there is no change of pressure or amount of gas, what is the new volume, V2V2V_2, of the gas? Express your answer with the appropriate units. A gas has a volume of 10 LL at 0 ∘C. What is the final temperature of the gas (in ∘C) if its volume increases to 39 LL ? Assume that the amount of the gas and its pressure remain unchanged.arrow_forwardHigh-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 PaPa) to about 60,000 kPakPa (60,000,000 PaPa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 5.50×108 Pa, what is its running pressure in torr? Express the pressure numerically in torr.arrow_forward
- A patient with Chronic Obstructive Pulmonary Disease, COPD, is using a 9.0 L tank filled with oxygen to help provide the needed oxygen to their blood. Calculate the moles of oxygen in the tank at room temperature, 295 K, and a tank pressure of 21.4 atm (R = 0.08206 L•atm/K•mol). Express you answer as three significant digits in moles (enter: mol).arrow_forwardA student breaks a thermometer and spills most of the mercury (Hg) onto the floor of a laboratory that measures 15.2 m long, 6.6 m wide, and 2.4 m high. The vapor pressure of mercury at 20°C is 1.7 x 10-7 atm. Calculate the mass of mercury vapor (in grams) in the room at 20°C. MW of Hg=200.6 g/mol; 1atm =101325 Pa; R=8.314 J/K mol;arrow_forwardIn 1783, Jacques Charles launched his first balloon filled with hydrogen gas, which he chose because it was lighter than air. The balloon, which had a volume of 31 000 L at STP, reached an altitude of 1000 m, where the pressure was 663 mmHg and the temperature was -3 ∘C. What was the volume, in liters, of the balloon at these conditions? Express your answer using two significant figures.arrow_forward
- Potassium permanganate reacts with oxalic acid (H2C2O4) in aqueous sulfuric acid according to the following reaction: 2 KMnO4(aq) + 5 H2C2O4(aq) + 3 H2SO4(aq) 2 MnSO4·H2O(s) + K2SO4(aq) + 10 CO2(g) + 6 H2O(g) What volume of 0.250 M KMnO4 solution is needed to react completely with 3.661 g of oxalic acid?
