Humid air is less dense than dry air because a molecule of water (m ≈ 18 Da) is less massive than either a molecule of nitrogen (m ≈ 28) or a molecule of oxygen (m ≈ 32). About 78% of the molecules in dry air are nitrogen (N 2). Another 21% of the molecules in dry air are oxygen (O 2). The final 1% of dry air is a mixture of other gases.
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.

A dagger, obelisk, or obelus † is a typographical mark that usually indicates a footnote if an asterisk has already been used. [1] The symbol is also used to indicate death (of people) or extinction (of species or languages). [2]
This is a list of countries by trade-to-GDP ratio, i.e. the sum of exports and imports of goods and services, divided by gross domestic product, expressed as a percentage, based on the data published by World Bank. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1.
In US and many international publications, BAC levels are written as a percentage such as 0.08%, i.e. there is 0.8 grams of alcohol per liter of blood. [ 1 ] [ 2 ] In different countries, the maximum permitted BAC when driving ranges from the limit of detection ( zero tolerance ) to 0.08% (0.8 g/L ).
In terms of judging a person's speed, the best method of timing is through lasers which start and stop the times when passed through. A laser start (from a stationary position) is more accurate for measuring pure speed as it does not register a runner's reaction time, however, this method of timing a 40-yard dash can affect the accuracy by as much as 0.5 seconds with the manual stopwatch method.
