With the data from the previous question, how many water molecules are there in one \(\mathrm{cm}^{3}\) (under standard pressure and temperature conditions)?
Previous Question
The mole is the unit for measuring the amount of substance, and is defined as the amount of substance that contains \(6.0225 \times 10^{23}\) elementary entities. This corresponds to the numerical value of Avogadro's constant, \(N_{A}\). The molecular mass of a substance is the ratio of the mass of a given amount of that substance to the number of moles of the same amount of that substance. It is commonly expressed in units of atomic mass (u). Molecular mass can be calculated as the sum of the atomic masses of all the constituent elements of the molecule. For example, the molecular mass of water \(\left(\mathrm{H}_{2} \mathrm{O}\right)\) is the sum of two atomic masses of hydrogen \((1.00794 \mathrm{u})\) and one of oxygen (15.9994 u). How many water molecules are there in one gram?
