How do they find the density of hydrogen
WebAug 15, 2024 · To solve for density, simply follow the equation d = m/v. For example, if you had a metal cube with mass 7.0 g and volume 5.0 cm3, the density would be (4) ρ = 7 g 5 c m 3 = 1.4 g / c m 3 Sometimes, you have to convert units to get the correct units for density, such as mg to g or in3 to cm3. Density can be used to help identify an unknown element. WebOct 30, 2024 · Swaczyna used SWAP’s measurements to derive the density of neutral hydrogen at the termination shock, where the solar wind butts up against the interstellar medium and abruptly slows down. After months of careful checks and tests, the number they found was 0.127 particles per cubic centimeter, or about 120 hydrogen atoms in a …
