Answer;
Molar mass of water is 18.02 g/mol
Explanation;
-Molar mass of a compound is determined by adding the relative atomic mass of each atom present in the compound. Molar mass of one mole of a compound, it is the weight in grams of 6.02 × 1023 atoms or molecules.
-Therefore; to calculate the molar mass of Water (H2O); we first know the RAM of hydrogen and oxygen which are; H=1.01 and O= 16.00
Since there is two atom of hydrogen and one atom of oxygen in water;
Then; the Molar mass of water will be; 2×1.01 + 1 ×16 = 18.02 g/mol
because the model makes the concepts easier to understand
Explanation:
A model would be useful because they make concepts easier to understand.
Models are abstractions of the real world.
- Scientists use model to make concepts easier to understand
- Models take parts of the real world and simulates them.
- They help remove the ambiguity that might be associated with studying the real world.
