A titration is often used to find the exact concentration of a solution. Worked example20shows the steps used to calculate the concentration of a solution of sodium hydroxide when it is neutralised by aqueous sulfuric acid of known concentration and volume. Question 17aThe equation for the reacti...
We often need to calculate the mass of a substance present in a solution of known concentration and volume. To do this we: ■ rearrange the concentration equation to: number of moles (mol) = concentration (mol dm–3) × volume (dm3) ■ multiply the moles of solute by its molar mass ...

Let's consider an example of a mole to mole conversion of abalanced chemical equation: {eq}CH_{4}\dotplus 2O_{2}\rightarrow CO_{2}\dotplus 2H_{2}O {/eq} We would interpret this in terms of moles as: "1 mole of CH4reacts with 2 moles of O2to form 1 mole of CO2and 2 ...
What is the mass of a liquid with a density of 2.12 g/ml and a volume of 53.0 ml? What are the differences between cellular respiration and photosynthesis? What is the conversion factor from km to ft? What is an example of a chemical equation?
Control rods nuclear reaction equation, moles liberated, pressure Homework Statement A control rod to limit the rate at which a nuclear reactor is working is made from boron which is sealed in a casing. A boron atom (105B) is able to capture a neutron; an atom of lithium (Li) and an ...
Volume is a dependent variable and its dependence on mole numbers is taken into account by solving a nonlinear equation (the volume balance equation) for pressure at each iteration level. By analyzing the block structure of the Hessian matrix in the constrained minimization of the Helmholtz free ...
