This could be the composition of some star, except that the hydrogen in a star is not likely to be molecular because of the high temperature. About the only sensible answer to the question as literally stated is "a mixture, probably of gases".
I think it's our Sun which gets heavier elements from fusion of hydrogen and other light elements.Edit: Our Sun does create helium from hydrogen by fusion, but that's all. The reason it has heavier elements is that these come from the nebula that formed the Sun. The heavier elements are thought to have come from stars that exploded as "supernovas", a long time ago.
Of the various types of matter that compose the interstellar medium, hydrogen, be it in atomic, molecular, or ionized form (e.g., protons) constitutes the vast majority of the material at over 90%. Helium forms about 9% and less than one tenth of a percent is heavier elements.
Each chloroform molecule (CHCl3) is composed of 25% hydrogen by mass. This is because the molecular weight of hydrogen is 1, with one hydrogen atom in each chloroform molecule, and the molecular weight of chloroform is 119.38.
For about 90% of a star's existence, it fuses hydrogen into helium, producing lots of heat. When the hydrogen starts to become depleted and the helium "ash" starts building up, the star may expand into a red giant, in which it fuses helium into carbon and heavier elements.
These elements are carbon ,hydrogen and oxygen.

Hydrogen and helium make up nearly 100 percent of the matter of the universe. Hydrogen comprises about 75 percent and helium makes up about 25 percent.
The sun's composition is dominated by two primary chemical elements, which together account for more than 98 percent of its mass. Hydrogen, the lightest and most abundant element in the universe, makes up approximately 74 percent of the sun's mass. Helium, the second lightest element, comprises about 24 percent of the sun's mass, bringing the total to 98 percent. The remaining 2 percent consists of various heavier elements, including oxygen, carbon, nitrogen, and iron, among others.
None. The sun is made of pure elements, mostly hydrogen, which fuse together, creating energy in the form of heat and light. When the hydrogen has fused into helium, the helium fuses into the heavier elements. Eventually, a couple billion years in the future, the sun will be made almost entirely of iron, at which point the fusion will cease and the sun will DIE. But you won't be around to see it. At no point does water form without it being immediately consumed and fused into heavier elements.
The Sun primarily consists of hydrogen (about 74% by mass) and helium (about 24% by mass), with trace amounts of heavier elements such as oxygen, carbon, neon, and iron. The high temperatures and pressures in the Sun's core allow nuclear fusion reactions to occur, converting hydrogen into helium and releasing energy in the form of light and heat.
The human body has many elements in it. It is 65 percent oxygen, 18 percent carbon, 9 percent hydrogen, 3 percent nitrogen, 1.5 percent calcium, 1 percent phosphorous, 0.4 percent potassium, and several other elements.
