The pH scale is used to indicate the acidity of a solution based on the concentration of hydrogen ions in the solution. The scale ranges from 0 to 14, and solutions with low pH numbers are more acidic than those with high pH numbers. Apple juice is a acidic solution with a pH of 3.3, indicating that it contains 1 × $10 ^ { - 3 }$ g of hydrogen ions per liter. Write this number in decimal form.
