Answer 2

Step-by-step explanation:

Given What is the mass of 30,000 molecules? Express you answer in scientific notation. Mass of one molecule of oxygen = 5.3 x 10^-23 gram

• Given Mass of one molecule of oxygen is 5.3 x 10^-23 gram
• Therefore mass of 30,000 molecules will be 30,000 x 5.3 x 10^-23
•                                                                = 3 x 10^4 x 5.3 x 10^-23
•                                              = 3 x 5.3 x 10^-23 + 4 (since a^m + a^n = a^m + n)
•                                                                  = 15.9 x 10^-19
•                   We need to express the answer in scientific notation,so we get
•                                                                  = 1.59 x 10^-18 gram
