200 Explanation: 2 is the one significant figure. The zeros are not significant. Round up because it is closer to 200 than to 100.
nano is 10 to the power of -9, micro is 10 to the power of -6 and so number of nano grams in i micro gram is
10 to the power of -6 divided by 10 to the power of -9, giving an answer of 1000
