Suppose that you developed a new temperature scale based upon the freezing and boiling point of ethylene glycol, which are -11.50, and 197.6, respectively. The temperature scale is called °M and has a value of 0°M at the freezing point and 100°M at the boiling point of ethylene glycol. What would the temperature be in degrees centigrade, if it was 20.916°M?
We are given an unknown antacid pill and through the procedure in this lab we determine its cost effectiveness to be 5.0x10-1 mole of acid/$. Can we also determine the number of moles of base in the pill
Determine the range of fat you might expect to obtain if you extracted fat from ten grams of nutmeg (Dried, ground nutmeg typically contains between 20-25% fat by weight.) Assume that your extraction is 95% effective.
An excited hydrogen atom emits light with a frequency of 1.141 multiplied by 1014 Hz to reach the energy level for which n = 4. In what principal quantum level did the electron begin?
a 1.70-g sample of a large biomolecule was dissolved in 14.0 g of carbon tetrachloride. the boiling point of this
The mitochondrion has two membranes, the inner and outer- the outer membrane is porous and enables many molecules to freely diffuse. The inner membrane is different from the outer membrane as it is only penetrable to o2
