Finding the relative formula mass of a gas from its density. This is about as tricky as it gets using the ideal gas A versatile Ideal Gas Laws calculator with which you can calculate the pressure, volume, quantity (moles) or temperature of an ideal gas, given the other three. Free online gas law calculator a.k.a. PV = nRT calculator which accepts different input metric units such as temperature in celsius, fahrenheit, kelvin; pressure in pascals, bars, atmospheres; volume in both metric and imperial units Se hela listan på chemistrypage.in Helium (med den kemiske formel He) er en kemisk inert gas (også kaldet en inaktiv gas), som spiller en meget vigtig rolle i mange forskellige aktiviteter og processer, fx MR-scannere, halvledere, fiberoptik, forskning, produktion af airbags, lækagesøgning samt varme- og overfladebehandling m.m.

. . Helium is also present as up to 7% of some natural gas sources, and large sources have over 0.5% (above 0.2% makes it viable to extract).

Molecular Formula: He. Formula SCOGS (Select Committee on GRAS Substances): Helium gas. FDA 21 CFR: 184.1355; 582.1355. So balloons filled with the monatomic gas can fly, while carbon dioxide weighs them down.

It displays red-orange color when exposed in an electric field.

Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V Helium can form unstable compounds, known as excimers with tungsten, iodine, fluorine, sulfur, and phosphorus when it is subjected to a glow discharge, to electron bombardment, or reduced to plasma by other means.
