n 10^-9
What is the multiple for milli?
m It is 1,000 times smaller or (10^-3) than the base unit
What is the multiple for centi?
c It is 100 times or (10^-2) smaller than the base unit
What does a kilo mean?
k It is 1,000 or (10^3) larger than 1 gram
1 k = 1,000 g
What is the multiple for mega?
M 10^6
1 M = 1,000,000 g
What is the SI unit for volume?
liter
What is the consequence of a liter?
1 mL = 1cm^3 = 1 cc
What is the units for density?
g/ cm^3 or kg/m^3
How do you go from kg/ m^3 to g/cm^3?
Divide by 1,000
How do you go from g/cm^3 to kg/ m^3?
Multiply by 1,000
What is the difference between empirical and molecular formulas?
The empirical formula gives the lowest reciprocal of each compound. The molecular formula gives you the chemical identity with the number of atoms in the molecule.
