Expert writing Tips

Best practice

When using "at density of", ensure the unit of measurement is clearly stated to avoid ambiguity. For example, specify "at a density of 1.2 g/cm³".

Common error

Avoid using alternative prepositions such as "in" or "on" in place of "at" with density. The correct phrasing is "at density of" to indicate a specific value.

Linguistic Context

The phrase "at density of" primarily functions as a prepositional phrase, modifying a verb or noun by specifying a quantitative measurement related to how closely packed a substance or population is. Ludwig examples show its prevalent use in describing experimental conditions.

Ludwig's WRAP-UP

In summary, the phrase "at density of" is a grammatically sound prepositional phrase predominantly used within scientific and technical writing to specify a quantitative measurement. Ludwig AI confirms its correctness and suitability for describing density in various contexts. While it's very common in scientific literature, its use is less frequent in news, business, and academic writing. For clarity, always state the units of measurement. Consider alternatives like "with a density of" for varied sentence construction. Remember that according to Ludwig, this phrase is most effective when precision and reproducibility are paramount.
