The correct answer is: "Noting the color of a solution as it is heated."

To understand this answer, let's first clarify what qualitative data is: Qualitative data is data that is descriptive, describes the attributes of something and it cannot be represented numerically. From the options listed the question, noting the color of a solution as it is heated, is the only statement that describes qualitative data. The color of a solution is an attribute of the solution that <em>cannot</em> be represented quantitatively-using numbers. On the other hand, the other options listed describe <em>quantitative data</em>, which are all measurable and can be represented numerically.

What is the volume of 0.120 g of C2H2F4<br> vapor at 0.970 atm and 22.4°C?<br> Answer in units of L.
ludmilkaskok [199]

Answer:

V= 0.031L

Explanation:

P= 0.97atm, V= ?, n= 0.12/98 =0.00122mol, R= 0.082, T= 22.4+273= 295.4

Applying

PV=nRT

0.970×V = 0.00122×0.082×295.4

Simplify the above equation

V= 0.031L
