					                   first round to 899 to 9 then count 5 decimal places left then put in scientific notation 9.0 x 10^-5
					                
					                
					             
					                   The density of hydrogen is 0.0000899 . Which of the following would be a reasonable estimate of the density of hydrogen?
9*10^-5 g/cm = 0.00009g/cm, which is approx equal to 0.0000899g/cm
