This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
Here "standard conditions" refers to temperatures of 25 °C and pressures of 1 atmosphere.Where data points are unavailable for 25 °C or 1 atmosphere, values are given at a nearby temperature/pressure.
The ASPCA estimates the annual cost of routine vet visits is $80-$250 for dogs and $110-$550 for cats depending on your pet’s age. Emergency vet visits can cost from $800-$1,500, and sometimes more.

This is a crucial property for common reversed phase chromatography since sample components are typically detected by UV detectors. Acetonitrile is more transparent than the others in low UV wavelengths range, therefore it is used almost exclusively when separating molecules with weak or no chromophores (UV-VIS absorbing groups), such as ...
