This ratio is the ratio of stoichiometric numbers in the equation. So the equation is: 2H2 + O2 -->2H2O We can still deduce the stoichiometry of this reaction even if we do not know the mass of oxygen that reacted. The ratio of hydrogen to water is 1 : 1. But there ...
Mole is a fundamental SI unit of measurement, used to measure the amount of any substance and is abbreviated as mol. One mole is equal to 6.022×1023 particles. This large particle is the Avogadro number of particles called the Avogadro constant. The mole is related to the mass of an ...

For the last problem, where you are given density and asked to find the number of molecules, you need to use the formula: density = mass/volume. Rearranging this equation, you get mass = density x volume. Plugging in the given values, you get 1.5 g = 1.33 g/cm3 x volume. So...
The grams to moles equation allows the simple conversion of grams to moles. Here is an illustration of how to find moles when given the mass in grams of a substance: The mass of one mole of lithium is 6.938 grams. If a sample of lithium (Li) weighs 100.0 grams, how many moles of ...
