What is 3 sig figs
True or false: a number in scientific notation can have a number written from 1 to 100 and multiplied by 10^#
What is false
If an object is 30g with a volume of 3mL, what is the density (g/mL)
30g/3mL = 10g/mL

What is 4.41
Write the number in scientific notation: 10.2
what is 1.02 x 10^1
A ball has a density of 0.1 g/mL and volume of 30mL. What is the mass?
0.1 x 30 = 3g
What do you have to multiply to get 1 kilogram (kg) to 1 gram (g)

A tungsten cube weighs 4.592 kg and has a density of 1.8368 kg/cm^3. What is the volume? (this is definitely not the actual density of tungsten)
4.592/1.8368 = 2.500 cm^3

gas
Give me a number that has 5 sig figs but ONLY 1 non-zero number in it
something like #0000. or #.0000
If I multiply 83.6 by 2.13 x 10^20, what is my EXPONENT when my answer is in scientific notation
what is 22
what is the REAL density of water?
really close to 1 but not 1 :D
the density of an object is 62.559 kg/cm^3. Convert this density to g/m^3
62.559 kg/cm^3 (10^3 g / 1 kg) (10^-2 cm / 1 m)^3 = 625.59 g/m^3
If something goes from gas, to liquid, to solid, am I absorbing energy or releasing energy? Aka is it an endothermic reaction or exothermic reaction for the original gas?
Exothermic, releasing energy
