Chemistry Calculator
Molar Mass & Mole Conversions
Smart Parser
Our algorithm understands complex chemistry syntax including nested brackets like Fe2(SO4)3 and Organic compounds like CH3COOH.
Accurate Weights
We use the 2024 IUPAC Standard Atomic Weights. For example, Chlorine is calculated precisely at 35.45, ensuring lab-grade accuracy.
Study Aid
Stop looking up periodic tables. Just type the formula and get the molecular weight instantly for your stoichiometry homework.
Chemistry Made Simple
Whether it's High School Stoichiometry or University Lab Work, calculate molecular weights and moles instantly with IUPAC precision.
Precise Data
Our database uses the latest IUPAC Atomic Weights (2024). E.g., Chlorine calculates as 35.45, not a rounded 35.5, ensuring your lab reports are 100% accurate.
Complex Support
No need to manually multiply brackets. Type Al2(SO4)3 and our parser automatically expands it to: 2 Aluminium + 3 Sulfur + 12 Oxygen.
Unit Conversion
Switch tabs to use the Grams to Moles Converter. Essential for finding limiting reagents in reaction equations quickly.
Examples You Can Try:
Type these formulas to test the parser's power:
- H2SO4 (Sulfuric Acid) - Standard industrial chemical.
- C6H12O6 (Glucose) - Essential organic compound.
- Ca(OH)2 (Calcium Hydroxide) - Handles parenthesis math flawlessly.
- CuSO4 (Copper Sulfate) - Uses Transition Metal masses accurately.
Your Digital Laboratory Partner
Stoichiometry calculations can be tedious and prone to manual errors. StudentCalcs simplifies lab work with precision engineering designed for chemistry majors.
Parser Engine
Don't pre-calculate brackets. Type complex strings like (NH4)2SO4 directly. Our Chemistry Calculator algorithm automatically expands the parenthesis and multiplies atomic weights.
IUPAC Standard
Accuracy matters. We use the latest periodic table weights (e.g., Chlorine = 35.45) rather than rounded integers, ensuring your lab results are accepted by professors.

How to Use This Chemistry Calculator?
Using an online Chemistry Calculator is faster than searching through a periodic table. Follow these steps:
- Select Mode: Choose between "Molar Mass" or "Grams to Moles" depending on your problem.
- Input Formula: Enter elements with proper capitalization. Use 'Cl' for Chlorine, not 'cl'. Case sensitivity helps us distinguish between Cobalt (Co) and Carbon Monoxide (CO).
- Analyze Result: View the breakdown. The tool shows the individual contribution of each element to the total molecular weight.

Frequently Asked Questions
Is this Chemistry Calculator suitable for exams?
While this tool provides instant answers, we recommend using it to verify your manual calculations during homework or lab reports. It helps you understand if you made a mistake in adding atomic masses.
What is Molar Mass vs. Molecular Weight?
They are numerically the same but differ in units. Molecular weight is the mass of one molecule (measured in amu), while Molar mass is the mass of one mole of a substance (measured in g/mol). Our Chemistry Calculator provides results in g/mol.
Does it handle hydrate compounds?
Yes. If you need to calculate CuSO4.5H2O, you can enter the atoms cumulatively or treat it as one formula. The parser sums up every atom found in the string.
