How many oxygen atoms are there in 2 molecules of Al2 SO4 3?
In this case, Al2 means 2 aluminums, (SO4)3 means 3 (SO4)s. The parentheses mean that the 3 has to be multiplied by whatever number of atoms you have of each element inside: 3×1 sulfurs, 3×4 oxygens. Now for the grand tally: 2 aluminum atoms + 3 sulfur atoms + 12 oxygen atoms = 17 atoms total in each molecule.Mar 1, 2001

What was the 0 originally called?
In pre-Islamic time the word ṣifr (Arabic صفر) had the meaning "empty". Sifr evolved to mean zero when it was used to translate śūnya (Sanskrit: शून्य) from India. The first known English use of zero was in 1598. The Italian mathematician Fibonacci (c.
Who invented 0?
"Zero and its operation are first defined by [Hindu astronomer and mathematician] BrahmaguptaBrahmaguptaHe is the author of two early works on mathematics and astronomy: the Brāhmasphuṭasiddhānta (BSS, "correctly established doctrine of Brahma", dated 628), a theoretical treatise, and the Khaṇḍakhādyaka ("edible bite", dated 665), a more practical text. Brahmagupta was the first to give rules to compute with zero.https://en.wikipedia.org › wiki › BrahmaguptaBrahmagupta – Wikipedia in 628," said Gobets. He developed a symbol for zero: a dot underneath numbers.Sep 18, 2017
What is a mathematical zero?
Zero is the integer denoted 0 that, when used as a counting number, means that no objects are present. It is the only integer (and, in fact, the only real number) that is neither negative nor positive. A number which is not zero is said to be nonzero.
Is 0 a number or not?
0 (zero) is a number, and the numerical digitnumerical digitA numerical digit (often shortened to just digit) is a single symbol used alone (such as "2") or in combinations (such as "25"), to represent numbers in a positional numeral system.https://en.wikipedia.org › wiki › Numerical_digitNumerical digit – Wikipedia used to represent that number in numerals. It fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems.
