Answer to Question #81270 in General Chemistry for pdm

Question

If you were to transfer 1ml of stock solution into 99ml of water, then a further 1ml of the new solution to 99ml of water, the total dilution would be 10 to the power of -x. What number does 'x' represent?

Answer 1

If you were to transfer 1ml of stock solution into 99ml of water, then a further 1ml of the new solution to 99ml of water, you will have 1/100th of 1/100th, which is (multiplying the fractions together) 1/10,000th. The total dilution would be 10 to the power -4.
