Explanation:

An observation that can be counted is known as quantitative observation. On the other hand, an observation that does not contain any numerical data is known as non-quantitative observation.

Therefore, given observations are classified as follows.

(a)  The Sun rises in the east - It is a non-quantitative observation as it cannot be measured.

(b)  A person weighs one-sixth as much on the Moon as on Earth - It is a quantitative observation as it can be measured because we know the mass of moon. Hence, we can find out the weight of person.

(c) Ice floats on water - It is a non-quantitative observation as it cannot be measured.

(d)  A hand pump cannot draw water from a well more than 34 ft deep _ It is a quantitative observation because it is measure that more than 34 ft deep water cannot be drawn by the pump.

What is the mass of 3.91 x 10^24 molecules of SeO2? The molar mass of SeO2 is 110.96 g/mol
Bad White [126]
3,91·10²⁴ = 39,1·10²³
-----------------------------

110,96g ----------- 6,02·10²³ molecules
Xg ------------------ 39,1<span>·10²³ molecules
X = (110,96</span>×39,1·10²³)/<span>6,02·10²³
<u>X = 720,687g</u>
