What is the mass of bromine in 50.0g potassium bromide?
The chemical formula of potassium bromide is KBr, showing that each formula unit contains equal numbers of potassium and bromine atoms. The gram atomic masses of potassium and bromine are 39.0983 and 70.904 respectively. Therefore, the mass fraction of bromine in KBr is 70.904/(70.904 + 39.0983) or about 0.644568. 50.0 g of potassium bromide therefore contains 32.2 g of bromine, to the justified number of significant digits.
What is the atomic number also equal to?
The atomic number is equal to the protons and electrons of an element.
How many Hydrogen atoms are in an Alkane with 16 Carbon atoms?
A non cyclic alkane always has a number of hydrogen atoms equal to 2c + 2, where c is the number of carbon atoms. Therefore, hexadecane, an alkane with 16 carbon atoms, will have 34 hydrogen atoms.
How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an element is equal to the number of protons plus the number of neutrons.
Is the number of protons equal to the number of ions in a neutral atom?
ions arent inside atoms. ions are atoms with a negative or positive charge. thanks for asking wikianswers and have a happy new year
How many moles of bromine atoms are in 2.60x102 grams of bromine?
2,60x102 grams of bromine (Br) is equal to 1,627 moles Br2.
One mole is equal to how many grams?
Its avogadros number which is 6.02 X 10^23 g/mol
How many protrons does bromine have?
The atomic number of an element is equal to the number of protons in a single atom. Therefore, Bromine has 35 protons.
Does the number of iron atoms in the reactants equal the number of iron atoms in the products?
no
What is Avogadros Theory?
Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. :)
What is Avogadros hypothesis?
the principle that equal volumes of all gases and vapors, under the same conditions of temperature and pressure, contain identical number of molecules.
How many atoms of hydrogen appear on each side of the equation?
The number of atoms in the reactants should equal the number of atoms in the products because the weight should be equal according to the Law of Conservation of Mass.
What is the mass of bromine in 50.0g potassium bromide?
The chemical formula of potassium bromide is KBr, showing that each formula unit contains equal numbers of potassium and bromine atoms. The gram atomic masses of potassium and bromine are 39.0983 and 70.904 respectively. Therefore, the mass fraction of bromine in KBr is 70.904/(70.904 + 39.0983) or about 0.644568. 50.0 g of potassium bromide therefore contains 32.2 g of bromine, to the justified number of significant digits.
Is the number of electrons equal to the number of protons in the atoms?
Yes :-)
How many atoms do there be in sulfur?
there are 16 atoms in sulfur, because the number of atoms in an element is equal to its atomic number, which is the number at the top of the square which is bolded
Is the atomic number the number of atoms it has?
The atomic number is equal to the number of protons.
What is the formula for chemical equations is balanced?
The number of reactants atoms must be equal to the number of products atoms.
