A snorkeler takes a syringe filled with 16 mL of air from the surface, where the pressure is 1.0 ATM, to an unknown depth. The volume of the air in the syringe at this depth is 7.5 mL. What Is the pressure at this depth? If the pressure increases by an additional 1 atm for eve...

Convert a pressure of 23.8 in. Hg into kilopascal. Ok so I looked up kilopascal and it Said 1 Kpa = 1000 pa So I began to set it up like this 23.8 / 29.2 x1000 am I correct Chemistry - DrBob222, Thursday, October 13, 2011 at 1:48pm I don't think that will get it. I would ...

DrBob222 I used 29.2 in Hg because my book gave me 1 atm = 29.92 in. Hg. But why did you use 1atm/760mm

How many moles of O2 are needed to form 3 moles of Al2O3 from the element
Chemistry
A thief uses a bag of sand to replace a gold statue that sits on a weight sensitive alarmed pedestal. The bag of sand and the statue have exactly the same volume 1.75 L. Assume that the mass of the bag is negligible. A) calculate the mass. ( density of gold = 19.3 g/cm3
Stoichiometry
I think I got it 6 mol A / 2 mol A x3 mol B = 9 mol B
Stoichiometry
So I have this question it reads Consider the generic chemical reaction How many moles of B are required to completely react with 2A + 3B ==> 3C 1. 6 mol of A 2. 2 mol of A I won't put them all just guide me in the right direction please
Stoichiometry
Consider the reaction between reactants S & O2 2S(s) + 3 O2(g) ==> 2 SO3(g) If a reactant vessel initially contains 5 mol S and 9 mol O2, how many moles of S, O2 and SO3 will be in the reaction vessel once the reactants have reached as much as possible? Assume 100% actual y...
