Introduction
Phosphoric acid (H3PO4) is a common inorganic acid with important applications in industry and biology. When working with chemical calculations, it's often necessary to determine quantities such as mass, volume, and molar mass for a given number of moles.
This page provides a comprehensive guide to calculating these quantities for 2.30 moles of H3PO4, along with a dedicated calculator for quick results.
Calculations for 2.30 Moles H3PO4
To calculate various quantities for 2.30 moles of H3PO4, we use the following formulas:
Molar Mass Calculation
The molar mass of H3PO4 is calculated by summing the atomic masses of its constituent atoms:
Molar Mass = (3 × Atomic Mass of H) + (1 × Atomic Mass of P) + (4 × Atomic Mass of O)
Using standard atomic masses: H = 1.008 g/mol, P = 30.97 g/mol, O = 16.00 g/mol
Mass Calculation
The mass of a substance can be calculated using the formula:
Mass = Number of Moles × Molar Mass
Volume at STP Calculation
The volume occupied by a gas at standard temperature and pressure (STP, 0°C and 1 atm) can be calculated using Avogadro's law:
Volume = Number of Moles × 22.414 L/mol
Using these formulas, we can calculate the molar mass, mass, and volume for 2.30 moles of H3PO4.
Formulas Used
The following formulas are used in the calculations for 2.30 moles of H3PO4:
Molar Mass Formula
Molar Mass = (3 × 1.008) + (1 × 30.97) + (4 × 16.00)
Molar Mass = 3.024 + 30.97 + 64.00
Molar Mass = 97.994 g/mol
Mass Formula
Mass = Number of Moles × Molar Mass
Mass = 2.30 × 97.994
Mass ≈ 225.78 g
Volume at STP Formula
Volume = Number of Moles × 22.414
Volume = 2.30 × 22.414
Volume ≈ 51.51 L
These formulas provide the basis for the calculations performed by the calculator on this page.
Worked Examples
Let's walk through a worked example to calculate the mass of 2.30 moles of H3PO4.
Example Calculation
Given:
- Number of moles = 2.30 mol
- Molar mass of H3PO4 = 97.994 g/mol
