How to multiply scientific notation

[From: ] [author: ] [Date: 12-08-05] [Hit: ]
00100= 1.1 x 10^(-3) * 6.02 x 10^23= 6.The answer is in molecules.......
In chemistry I have to do problems like this. (0.00100 mole) x (6.02 x 10^23 molecules/1 mole) but the problem is I forgot how to multiply non scientific notation with scientific notation.

Convert the non-SN to SN then add the powers of ten and multiply the other numbers , then adjust the powers of 10 to give one digit (1 to 9) before the decimal point.

0.00100 = 1.0 * 10^(-3)

1 x 10^(-3) * 6.02 x 10^23 = 6.02 x 10^20 (no need to adjust the powers of ten)

The answer is in molecules.
