Simple Math question thats bsing me
Tungsten has a density of 1.94 10^4 kg/m^3. What is the density of tungsten in units of g/cm^3?
In regular notation thats 19400 kg/m^3
I need it in g/cm^3
First: I converted it to kg/cm^3 which is 194 kg/cm^3.
Second now I convert it to g/cm^3 which the answer should be 194000 g/cm^3.
I keep getting told its wrong. Wtf its right.
There are 1000 grams in 1 kilogram.
There are 100 centimeters in 1 meter.
Someone do it and tell me what I already know which it is 194000 g/cm^3.

When dealing with a computer it only handles up to so much accuracy when dealing with floating point numbers. So, sometimes when calculating, zero may not actually equal zero. Don't know if that explains your problem with why your calculations were wrong on the computer. But it just makes me feel better to pretend that I know what I'm talking about.

1 m^3 = 1m x 1m x1m = 100cm x 100cm x 100cm = 1,000,000 cm^3 not 1m^3 = 100cm^3
imagine a box that is 1 meter tall, wide and long, so that is 1 cubic meter.
now that is alot bigger then a box is 1 cm tall, 10 cm long, and 10 wide, that box would be 100 cubic centimeters.
1 cm^3 = 1 cc = 1 cubic centimeter = 1 mL
thus, your 19400 kg/m^3 equals (19400,000g)/(1,000,000cc) or 19.4g/cc
19.4g/cm^3 is your answer.
