To determine the number of moles in a substance when given its volume, you can use the formula: moles volume (in liters) / molar volume (in liters per mole). The molar volume is a constant value that depends on the substance being measured.

To determine the volume of a substance when given the molarity and moles, you can use the formula: volume moles / molarity. This formula helps calculate the volume of a solution based on the amount of substance (moles) and its concentration (molarity).
The amount of substance in a given unit of volume is called concentration. It is typically expressed as the number of moles of a substance per unit volume, such as mol/L (molarity) or mol/cm³.
The density of a substance is determined by its mass and volume. Density is calculated by dividing the mass of the substance by its volume. The denser a substance is, the more mass it has in a given volume.
To determine the number of moles in a given sample, you can use the formula: moles mass of sample (in grams) / molar mass of the substance. This formula helps you calculate the amount of substance in terms of moles based on its mass and molar mass.
That would be the concentration of the substance, commonly expressed in units like moles per liter or parts per million. It tells us how much of the substance is present in a specific volume of the solution.
