How do we find out the composition of stars?
Spectral analysis.
The spectral type of a star measure?
The spectral type of a star is what measures its chemical composition. The visible light that bounces off of it can be used to determine the composition.
The set of spectral lines that we see in star's spectrum depends on the stars?
Chemical composition ;-)
How do astronomers determine the composition of distant celestial objects?
Spectroscopy is the systematic study of spectra and spectral lines. Spectral lines are used to provide evidence about the chemical composition of distant objects. So the answer to your question is through spectroscopy.. not spectrometry like the previous editor posted.
Which physical property of a star does the spectral type measure?
Composition.
What provides info about the chemical composition of stars?
The composition is determined by spectral analysis.

Suppose you want to know the chemical composition of a distant star Which piece of information is most useful to you?
A telescope, whose light output would be sent through a spectral analysis machine of some type. That analysis of the emission spectra of the star would be compared to the known spectra of the elements to find the composition of the star.
What are some star characteristics that can be identified by spectral analysis?
it determines their composition and age and direction of shift
The set of spectral lines that we see in star's spectrum depends on the stars?
Chemical composition ;-)
How did astronomers in the 19th century gather information about the chemical composition of stellar objects?
There is one way for gathering information about chemical composition of stellar objects - spectral analysis! Astronomical spectroscopy began with Isaac Newton's initial observations of the light of the Sun, dispersed by a prism. He saw a rainbow of colour, and may have seen absorption lines. The absorption lines in stellar spectra can be used to determine the chemical composition of the star.
What is an emission spectra used for?
The emission spectrum can be used to determine the composition of a material
What do astronomers use to determine the chemical composition in star?
The light that comes from the star. The light is spread out into its spectrum and the pattern of spectral lines allow the composition (and temperature) to be determined. The temp can also be found by looking at the black body curve for the star (also from spectrum), or, by looking at the color of the star (difference in intensity of the light through two different color filters typically B and V.

Is the flame test accurate?
Not as accurate as a spectral analysis.
