science chemistry# How do you find the molecular weight of h2so4?

Last Updated: 29th January, 2020

**Molar mass of H2SO4**can be calculated byaddingthe respective

**molar masses**of all the elementsconstitutingit.

**Molar mass of**H(x2)+

**Molar mass of**Sulphur(x1)+

**Molar mass of**Oxygen(x4). =>98g/mol.

People also ask, what is the molecular weight of h2so4?

98.079 g/mol

Additionally, how do I calculate molecular weight? **Calculate** the total mass for each element inthe**molecule**. Multiply the atomic mass of each element by thenumberof atoms of that element: (Atomic Mass of Element) x (# ofatoms ofthat element). Do this for each element in the**molecule**. Inour carbon dioxide example, the mass of thesingle carbon atom is12.011 amu.

Similarly one may ask, how do you find the equivalent weight of h2so4?

**Equivalent weights** may be calculated frommolarmasses if the chemistry of the substance is well known:**sulfuricacid** has a molar **mass** of 98.078(5)gmol^{−}^{1}, and supplies two molesofhydrogen ions per mole of **sulfuric acid**, soits**equivalent weight** is 98.078(5)gmol^{−}^{1}/2**eq**mol^{−}^{1} = 49.039(3)g**eq**^{−}^{1}.

What is the percentage oxygen by weight in h2so4?

Percent composition by element

Element | Symbol | Mass Percent |
---|---|---|

Hydrogen | H | 2.055% |

Oxygen | O | 65.251% |

Sulfur | S | 32.693% |
