(126)(1.3)=163.8
divide 163.8 by 450 = .364 which is the answer
The molarity of the diluted solution equals: c2 = (c1*V1)/V2, since the amount of glucose (n) is the same in both solutions.
(126ml)(1.0M glucose) = (550.0ml)( XM glucose)
0.229M glucose ( should be two sigi figi )
123 ml * 1.0 (conc.) = 550.0 ml * X (conc.)
X = 123/550 = 0.224 (conc.)
4,500 has two significant figures.
A 4500 watt element will work on a 20 amp breaker if it operates at 220 volts or less. It will simply trip the breaker if the load is greater than 20 amps at 220 volts.
When the fuel is used with oxygen, flame temperatures can range from 4500 to 5600 degrees Fahrenheit, depending on the fuel used. (2500 - 3100 degrees Celsius)
Mercury (Hg)Historically, mercury was used extensively in hydraulic gold mining in order to help the gold to sink through the flowing water-gravel mixture. Thin mercury particles may form mercury-gold amalgam and therefore increase the gold recovery rates. Large scale use of mercury stopped in the 1960s. However, mercury is still used in small scale, often clandestine, gold prospection. Total use of mercury in placer mining in California has been estimated to more than 4500 tons (10,000,000 lbs). Mercury was also used in silver mining. And in the process of gilding (gold plating) silver plate.Cyanide (HCN)Cyanide solutions are used in the extraction of gold from low grade ore. The reaction in the Elsner Equation is as follows :4Au + 8NaCN + O2 + 2H2O -> 4NaAu(CN)2 + NaOHThe gold is then recovered from the the soluble aurocyanide complex by plating out.An Aside: Walking across tailings area you can smell the sweet cyanide aromaAqua Regia (HNO3 + HCl Solution)This is the historic method of dissolving gold . Higraders in gold camps ofhen are found by watching chimneys to see the brown nitrous fumes from boilling off the acid to recover the gold.
As a general rule stainless steel is a little less than twice as dense as titanium. One method for determining the material makeup of an object would be to calculate its density. To do this the object would first have to be weighed, and its mass recorded (on earth with a relatively constant rate of acceleration due to gravity of 9.8 m/s^2 mass can be determined using a scale). Next, the volume needs to be determined. This could either be calculated for simple shapes by taking measurements and then applying formulas for volume of shapes or by submersing the object in a fluid and measuring the displacement. After determining the objects mass and volume, the density can then be calculated by dividing the weight by the volume. Stainless steel has a density of between 7480 and 8000 kg/m^3 and titanium 4500.
30% of 4500= 30% * 4500= 0.3 * 4500= 1350
6% of 4500= 6% * 4500= 0.06 * 4500= 270
36% of 4500= 36% * 4500= 0.36 * 4500= 1,620
21% of 4500= 21% * 4500= 0.21 * 4500= 945
