The density of a 20 percent by mass ethylene glycol solution in water is 1.03gml Find the molarity of the solution?
(0.23)(1.04g/mL)(1000mL/L)(1 mol C2H6O2/62g C2H6O2) = 3.86 M
What mass of PCl 5 will be produced from the given masses of both reactants?
What mass of will be produced from the given masses of both reactants? 28.0 g/P4 / 123.9 g/P4 = 0.2260 moles/ P4 0.2260 moles /P4 * 4 moles PCl5/1 mole/P4=0.904 moles/PCl5 54.0 g/Cl2 / 70.9 g/Cl2 = .7616 moles/Cl2 .7616 moles / Cl2 *4 moles PCl5/10 moles Cl2=.30 This is about limiting reagents You need to use 2P + 5Cl2 --> 2PCl5 [or P4 + 10Cl2 --> 4PCl5 if you prefer] that tells you that 2P = 62g needs 5Cl2 = 355g Cl2 to react 69.3g
How many atoms are present in 31 grams of magnesium fluoride?
MgF2 has a molecular weight of 24+19*2 = 62g. Thus, 31 grams of MgF2 represent .5mol. There are 6.022*10^23 particles per mole. Since MgF2 has three atoms in it, we can find the number of atoms by the following: (.5 mol)(6.022*10^23 particles/mol)(3 atoms in MgF2) = ... Enjoy your free high school chemistry answer!
When 46g of sodium were exposed to dry air 62g of sodium oxide formed how many grams of oxygen from the air were used?
16 grams? I would purpose that this has a little something to do with the law on conservation of mass. I could always be wrong though...
What mass of sodium oxide could be made from 115grams of sodium?
Balanced equation: 2Na(s) + O2(g) ---> Na2O(s)moles Na = 115 g x 1 mol/23 g = 5 molesmoles Na2O possible = 1/2 x 5 moles = 2.5 moles (b/c the mole ratio of Na2O:Na is 1:2)mass Na2O possible = 2.5 moles x 62 g/mole = 155 grams (assuming O2 is not limiting)
