- A graduated cylinder (measuring cylinder) contains 27 mL of water at 25 °C and the mass of the water is 26.92 g. A sphere of iron with a diameter of 18.0 mm is added to the water in the graduated cylinder. The total mass of the water and the iron is 50.92 g. (The volume of a sphere is given by the expression: V = (4/3)ar³). (i) Calculate the total volume of the water and the iron in the graduated cylinder. (ii) Determine the density of iron at 25 °C? Show your calculations. (iii) Without doing any calculations, what do you think the density of 48.00 g of iron is at the same temperature? Explain your answer.arrow_forwardMethanol (CH3OH) is a liquid at room temperature with a density of 7.91 ×102 kg/m3.In a certain experiment, from the reaction of 2.91 mL of methanol with 2.88 g of oxygen, 2.27 gof carbon dioxide was obtained.(a) What type(s) of chemical reaction is (are) occurring in this experiment?(b) What equipment do you think was used to measure the volume of methanol in thisexperiment?(c) Calculate the percent yield of the carbon dioxide in this experimentarrow_forwardThe distance between two adjacent peaks on a wave is called the wavelength.(a) The wavelength of a beam of ultraviolet light is 247 nano-meters (nm). What is its wavelength in meters?(b) The wavelength of a beam of red light is 6760 pm. What is its wavelength in angstroms (Å)?arrow_forward
- (a) Carbon monoxide (CO) is a poisonous gas because it binds very strongly to the oxygen carrier hemoglobin in blood. A concentration of 8.00 × 102 ppm by volume of carbon monoxide is considered lethal to humans. Calculate the volume in liters occupied by carbon monoxide in a room that measures 17.6 m long, 8.80 m wide, and 2.64 m high at this concentration.(b) Prolonged exposure to mercury (Hg) vapor can cause neurological disorders and respiratory problems. For safe air quality control, the concentration of mercury vapor must be under 0.050 mg/m3 . Convert this number to g/L. (c) The general test for type II diabetes is that the blood sugar (glucose) level should be below 120 mg per deciliter (mg/dL). Convert this number to micrograms per milliliter (μg/mL).arrow_forward(a) The density of iron is 7.874g/cm^(3). Create two conversion factors from the density; (b) What is the volume of 38g of iron?arrow_forwardA flask weighs 64.25 g when empty and weighs 91.75 g when filled with water at 20oC. However, when the flask is filled withthe same volume ofisopropyl alcohol at the same temperature, the combinedmass of flask and alcohol is 86.00 g. (a) If the density of water is 0.99823 g/mL at 20oC, what is the volume of water that filled the flask? (b) Determine the density of isopropyl alcohol at 20oC.arrow_forward
- A gasoline station in Manila, Philippines, charges 38.46 pesos per liter for unleaded gasoline at a time when one U.S. dollar (USD) buys 47.15 pesos PHP). The car you are driving has a gas tank with a capacity of 14 U.S. gallons and gets 24 miles per gallon. (a) What is the cost of unleaded gasoline in Manila in USD per gallon? (b) How much would a tankful of unleaded gasoline for your car cost in USD? (c) Suppose that you have only PHP 1255 (a day’s wage for an elementary school teacher) and the car's tank is almost empty. How many miles can you expect to drive if you spend all your money on gasoline?arrow_forwardCalculate the number of Kilograms of NaF per year of 100,000people if the daily consumption of water per person is 132.0 gallons (Sodium Fluoride is 45.0 percent Fluorine by mass. 1 gallon =3.79L, 1year+365 days,density of water+1.0g/larrow_forwardA metal object of an irregular shape has a mass of 31.5 grams. When the metal is added to water in a graduated cylinder, the volume of water increases from 5.28 mL to 7.61 mL. (A) How much water does the metal displace? (B) Calculate the density of the metal. (C) Is the metal made of platinum? Explain. (Hint: the density of platinum = 21.4 g/cm³)arrow_forward
