If each book had a mass of 100 grams, all of them would have a total mass of 10 93 kilograms. In comparison, Earth's mass is 5.97 × 10 24 kilograms [5], the mass of the Milky Way galaxy is estimated at 1.8 × 10 42 kilograms [6], and the total mass of all the stars in the observable universe is estimated at 2 × 10 52 kg.

A decimal separator is a symbol that separates the integer part from the fractional part of a number written in decimal form (e.g., "." in 12.45). Different countries officially designate different symbols for use as the separator. The choice of symbol also affects the choice of symbol for the thousands separator used in digit grouping.
Any real number can be written in the form m × 10 ^ n in many ways: for example, 350 can be written as 3.5 × 10 2 or 35 × 10 1 or 350 × 10 0. In normalized scientific notation (called "standard form" in the United Kingdom), the exponent n is chosen so that the absolute value of m remains at least one but less than ten ( 1 ≤ | m | < 10 ).
The results found that 8.6% of women and 10.1% of men had at one point in their life experienced some form of homosexuality. Of this group, 87% of women and 76% of men reported existing same-sex attractions , 41% of women and 52% of men had sex with someone of the same gender, and 16% of women and 27% of men identified as LGBT .

In chemistry the negative of the decimal logarithm, the decimal cologarithm, is indicated by the letter p. [63] For instance, pH is the decimal cologarithm of the activity of hydronium ions (the form hydrogen ions H + take in water). [64] The activity of hydronium ions in neutral water is 10 −7 mol·L −1, hence a pH of 7. Vinegar typically ...
One study found that between October 7 and November 14, 2016, while one in four Americans visited a fake news website, "Trump supporters visited the most fake news websites, which were overwhelmingly pro-Trump" and "almost 6 in 10 visits to fake news websites came from the 10% of people with the most conservative online information diets."
