How many atoms are in a molecule of borax Na2B4O7?
A molecule of borax, Na2B4O7, contains a total of 13 atoms. This can be calculated by adding the number of each type of atom present in the molecule: 2 sodium atoms (Na), 4 boron atoms (B), and 7 oxygen atoms (O), for a total of 13 atoms. Each element's subscript in the chemical formula indicates the number of atoms of that element in the molecule.
What is the empirical formula of a compound that contains 57 percent sulfur and 43 percent oxygen by mass?
Since the atomic mass of sulfur is very close to twice the atomic mass of oxygen, the ratio of numbers of oxygen atoms to numbers of oxygen atoms is close to 43:28.5. The closest ratio of small integers is 3:2; therefore the empirical formula is S2O3.
How many mole of atoms are contained in 25.0 g naoh?
To find the number of moles of NaOH in 25.0 g, you first need to determine the molar mass of NaOH (40.00 g/mol). Then, divide the given mass by the molar mass to get the number of moles: 25.0 g / 40.00 g/mol = 0.625 mol of NaOH.
Is borax a atom?
No. It is a molecule and consists of 43 atoms.

How many protons Neutrons and electrons does 43 20 Ca have?
The isotope (^{43}_{20}\text{Ca}) (calcium-43) has 20 protons, which is characteristic of all calcium atoms. To find the number of neutrons, subtract the atomic number from the mass number: (43 - 20 = 23) neutrons. Since it is a neutral atom, it also has 20 electrons. Thus, calcium-43 has 20 protons, 23 neutrons, and 20 electrons.
