How can a chemical formula be experimentally determined? How can I calculate the molar volume of Hydrogen gas? How can I understand Hess's law step by step? How do ionization and dissociation.
The stoichiometry of the formula determines the respective concentration of the ions in solution. How would this change if we had for instance, [NaCl (aq)]=0.450molL^-1; what are [Na^+] and [Cl^-]?
"170 mL" Your strategy here will be to write a balanced chemical equation for this single replacement reaction use the molar volume of a gas at STP to find the number of moles of hydrogen gas present.
In order to find the vapor density of aluminium chloride, you must first calculate its molar mass. Another look in the periodic table will show that chlorine has a molar mass of approximately #"35.45 g mol"^ (.
Let the molecular formula of HC be CxH y And the balanced equation of the combustion reaction of the HC in oxygen is CxH y + (x + y 4)O2(g) → xCO2(g) + y 2H 2O(l) So by this equation the.
65.0 "g N"_2 Any time you want to convert between moles and grams of a substance, you must know that substance's molar mass, which is the mass of one mole of that substance. (One mole is equal to.
You'd need 67 g of potassium nitrate to make that respective solution. Molarity is defined as moles of solute, in your case potassium nitrate, per liters of solution. Since you know the volume of the final.
The volume of the 40 molar solution required is "0.005 mL" or "5 mL". Refer to the explanation for the process. The symbol "M" represents molarity, which is "moles of solute"/"liters of solution". A "0.10.
