<span>Carrier Gas, Flow Controller, Column, Detector, Recorder

</span>First we have a cylinder containing the carrier gas. From there, the carrier gas goes to the flow controller, which determines how much carrier gas we are entering into the column (it doesn’t let more gas pass through). Then, the carrier gas enters the column, which is the most important part of the device. The sample enters the column from another place: the injector. Then, the sample and the carrier gas go together across the column. The interactions between the sample and the column will determine how fast each sample component goes through the column, and so: which component gets out earlier. So, at the end, you will have isolated each substance. Then, each one passes (alone) through the detector, which measures something about the sample – this information will let you know which substance it is. Finally, the recorder provides you with the information the detector has found. Nowadays, the recorder is a computer. In the “stone age” they just used a rudimentary printer.

The accepted value for the density of iron is 7.9 g/mL. Four student groups examine the density of iron in the lab. Which of the
nalin [4]

For 5.43 g/mL and 5.44 g/mL =  0.01 the least diff and most precise.

First of all, precision is determined by the difference in the two obtained values. If the difference between the two values obtained is less, then precision is more. If the difference between the two values obtained is more, then precision is less.

For 5.43 g/mL and 5.44 g/mL , we can see that the difference between these two data is 0.01

For 7.98 g/mL and 7.91 g/mL , we can see that the difference between these two data is 0.07

For 7.65 g/mL and 7.64 g/mL , we can see that the difference between these two data is 0.01

For 7.06 g/mL and 7.03 g/mL , we can see that the difference between these two data is 0.03

As we can see that, the most difference between the data is 0.07 between 7.65 g/mL and 7.64 g/mL and thus, they are least precise.

Each student in a class placed a 2.00 g sample of a mixture of Cu and Al in a beaker and placed the beaker in a fume hood. The s
Aleks [24]

Answer:

Percentage mass of copper in the sample = 32%

Explanation:

Equation of the reaction producing Cu(NO₃) is given below:

Cu(s)+ 4HNO₃(aq) ---> Cu(NO₃)(aq) + 2NO₂(g) + 2H₂O(l)

From the equation of reaction, 1 mole of Cu(NO₃) is produced from 1 mole of copper. Therefore, 0.010 moles of Cu(NO₃) will be produced from 0.010 mole of copper.

Molar mass of copper = 64 g/mol

mass of copper = number of moles * molar mass

mass of copper = 0.01 mol * 64 g/mol = 0.64 g

Percentage by mass of copper in the 2.00 g sample = (0.64/2.00) * 100%

Percentage mass of copper in the sample = 32%
