This problem is providing the length in inches of a rod and it is being required to convert it to centimeters. According to the following, the answer will be 43.7 cm:
<h3>Units conversion:</h3><h3 />
In science, we use units conversion to represent measurements in different types of units depending on a specific requirement. To do so, we use conversion factors based on equivalence statements, relating the required unit with the given one.
In this case, the equivalence statement between inches and centimeters is 2.54 cm = 1 in and we can use it to get the answer as shown below:

Explanation:
2. 
First, we need to find the number of moles of 
at 300K and 1.5 atm using the ideal gas law:
Now use the molar ratios to find the number of moles of ethane to produce this much .
Finally, convert this amount to grams using its molar mass:
3. 
Convert 75 g Zn into moles:
Then use the molar ratios to find the amount of H2 produced.
Now use the ideal gas law 
to find the volume of H2 produced at 23°C and 4 atm:
Answer:
Because the student made use of scientific instruments in one case and his senses in the other.
Explanation:
Scientific experiments involve making observations, which is key to the outcome of any experiment. According to the scientific method, collecting of data is one of the steps in fulfilling the scientific procedure. One way to collect data is by using scientific instruments to measure, which is then recorded. This is the case for the WEIGHT of the sugar the student recorded.
Another way to collect data is by making use of the senses e.g eyes, nose, skin etc. to observe and record the perceived information. Therefore, the pieces of information collected by the student represent DATA because he made use of his senses and scientific instruments.
