Answer in scientific notation

Question

Convert 35dg to kg

Convert 0.003ml into microliter

Convert 5nm to micrometer

Convert 750 microliter to centiliters

Convert 100x10^3 m into km

Answer 1

Using dimensional analysis...

35 dg x 1 g / 10 dg x 1 kg / 1000 g = 0.0035 kg = 3.5x10^-3 kg

0.003 ml x 1 ul / 1x10^-6 ml = 3000 ul = 3x10³ ul

5 nm x 1 um / 1x10³nm = 5x10^-3 nm

750 ul x 1 ml / 1x10⁶ ul x 0.1 cL / ml = 7.5x10^-5 cL

100x10³ m x 1 km / 10³ m = 100 km
