Two units of distance used by scientists to describe distances in space are the light-year and astronomical unit. Why do scientists use the light-year instead of Astronomical Units to measure the distances between stars?
The speed of sound is too slow.
Telescopes can measure only in light years
Distant stars can only be seen if there is light
The smaller numbers that result from measuring with larger units are easier to use

That’s the one, good luck!
Ответ:
0.737M
Explanation:
C1V1=C2V2
2.50 x 0.442 = C x 1.5
1.105 = C x 1.5
C = 1.105/1.5
C = 0.737M
