The phrase "amounts per volume" is correct and usable in written English.
It can be used in contexts where you are discussing concentrations, measurements, or quantities of a substance in relation to a specific volume.
Example: "The solution contains 5 grams of salt per volume of 1 liter of water."
Alternatives: "concentration per volume" or "quantity per volume".
To assist in emulsion removal in the organic phase, 2% (volumer per volume) amount of ethanol was added to disrupt surface tension of the emulsion and clear the organic phase.
To study the influence of the particle size, the Bac-1 cells were incubated with different sized gold colloids at concentrations yielding about equal amounts of gold per volume in the incubation suspension.
As a result, the adsorbed amount per unit volume of silica gel in the adsorption dehumidification systems was increased and the quantity of regeneration heat needed was decreased.
It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.
Liver has little or no action in human secondary anaemias, but is effective in certain other anaemias which, like pernicious anaemia, are characterised by an increase in the amount of haemoglobin in each red blood cell although the total amount per unit volume of blood is diminished.
The density of mass (amount of mass per volume of space) that is required to halt the expansion is often called the "critical density". If the universe is more dense than critical, the gravity of all the stuff in the universe will be able to overcome the expansion, causing it to stop, and eventually re-collapse.
Although these synapses with large recycling pool sizes were rare, they were densely arranged and thus exhibited a high amount of release per volume.
Some difference in rearing conditions (possibly the amount or calories per volume of the chow provided) might underlie the difference in the phenotype of OLETF at similar ages.
Controls were fed ad libitum with a semi-liquid diet without EtOH and providing the same amount of calories per volume.
The treatments were the same as in the growth experiment (Table 3) and amounts of fertilizer added per volume of soil (mL per L soil) corresponded to those in the growth experiment.
