1.256 μL → ?mL
2.2007 hm → ?dm
3..00096 g → ?mg
Answer using scientific notation
4.15,002,000 =
5.98,005,000,000,000,000 =
6..00000000920 =
7.How many hours will you spend in this class during the school year? (1 school year = 181 days)
8.A leaf sample on the balance reads 1.05 g how much does it weigh?
Fw = m • ag
Ha! A balance measures mass not weight! If you insist on using the term weight use the above formula; where Fw = weight (in Newtons), m = mass in kg and ag = 9.8m/s/s (acceleration of gravity on Earth)
•Remember, every test will include dimensional analysis problems and I require you to show the math work for full credit. This will be crucial preparation for those of you taking physics or chemistry Jr & Sr year.
