Read carefully. Twice as much as one million trillion is two million trillion. One thousand times as much is 1000 million trillion. One million times as much is 1,000,000 million trillion, which is the same as one trillion trillion. Thus, one trillion trillion is a million times greater than a million trillion. Got that? So how many more water molecules than impurity molecules are there in a glass of water that is 99.9999 percent pure?

Question

Quizplus · Accepted Answer

The question provides irrelevant information about the comparison of numbers to confuse the reader. The important information is that the water in the glass is 99.9999 percent pure. This means that only 0.0001 percent of the glass contains impurities. Therefore, there are 1,000,000 (one million) times more water molecules than impurity molecules in the glass of water.
