Question- Determine the molar mass of chloroform gas if a sample weighing 0.389 g is collected in a flask with a volume of 102 cm3 at 97°C. The pressure of the chloroform is 728 mmHg.
Here is the problem which I am struggling on, please help me!
How would I do that? I have a diagram for a trigonal bipyramidal crystal field and two values are on the diagram. There's a delta 0.19 and a delta 0.79.
how many moles of excess reactant are present when 2.90*10^2 ml of .182 M sulfuric acid reacts with .423 L of .170 M sodium hydroxide to form water and aqueous sodium sulfate?
A specific brand of gourmet chocolate candy contains 7.00 g of dietary fat in each 22.7 g piece. How many kilograms of dietary fat are in a box containing 3.00 lb of candy? Express your answer numerically in kilograms.
The subsequent reaction has a Kc = 1.20 x 10-6 at 300 K. If the initial concentrations of Ao = 0.200 M and Bo = 0.100 M, Define what is the equilibrium concentration of C. A+B ->
