Answer:

Explanation:
Hello,
In this case, considering that the density is defined as:

Thus, since 1 kg equals 1000 g and 1 L equal 1000 mL, the required density in g/mL turns out:

Take into account that since 0.65 L has two significant figures, the result is also shown with two significant figures.
Regards.
48.400 g of nitrogen is 76.0
Manganese since the atomic number is 25
Q, R, S, P is the order of apparent magnitude of the stars, starting from the least to the greatest.
Answer: Q, R, S, P
<u>Explanation:</u>
The apparent magnitudes of the star is the brightness calculated by an observer at a particular distance from the Earth. The smaller the distance between the star and the Earth, the greater the apparent brightness.
So , from the given distance (in light years), Q,R,S,P is the answer (least to the greatest apparent magnitude) (distance is greatest to least).
