I cannot figure this out. It seems so simple, and I should know it.
The density of tungsten is 19.3g/cm^3
Express this value in lb/ft^3.
I did 19.3g/cm^3 x 2.54cm/inch x 12 inches/1 foot = 588.264.
Now 19.3g x 1 ounce/28g x 16 ounces/lb.
= 11.03.
After reading my answer key, the answer says it is 1.21 x 10^3 lb/ft^3.
I cannot for the life of me figure out what I am doing wrong. Please help.
