QUESTION:
Problem 42P
How many moles of water are there in 1.000 L? How many molecules?
ANSWER:
Solution 42P
Step 1 of 3:
Our aim is to calculate the number of moles and the number of molecules in a liter of water.
The density of water ⍴ = 1000 kg/m3
The molar mass of a single H2O molecule M = 18 g/mol = 18 x 10-3 kg/mol
The volume of water V = 1 L = 10-3 m3
