Cubic metre is the metric unit for measuring volume. The cubic centimetre has a particular nomenclature called a millilitre.
The 3-dimensional space that is occupied by matter or surrounded by a surface is measured in volume, which is expressed in cubic units. A derived unit called the cubic metre serves as the SI unit of volume.
A unique designation for the cubic decimeter is the litre. To reduce the chance of confusion between the lowercase letter "ell" (l) and the number one (1), the symbol for the litre is an uppercase letter "ell". The litre cannot be represented by the script letter l (l).

Mass of a substance = Moles of a substance × molar mass of a substance
We have 0.94 moles of NaHCO3. The molar mass of NaHCO3 is the sum of the atomic masses of the elements comprising NaHCO3, which is approximately 84.007 g/mol.
The mass of 0.94 moles of sodium bicarbonate is therefore (0.94 moles NaHCO3)(84.007 g NaHCO3/mol NaHCO3) = 78.97 ≈ 79 grams of sodium bicarbonate.
