This is, in fact, the definition of a mole. In order to have one mole of any molecular substance, you need to have #6.022 * 10^ (23)# molecules of that substance #-># this is known as Avogadro's …

"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 …

This implies that, at equilibrium, the solution contains #0.60# moles of hydronium cations and #0.60# moles of #"A"^ (-)# #-># this is the case because for every #1# mole of weak acid that …

Dec 24, 2017 · One "mole" of CO2 thus contains one "mole" of carbon, C, and one "mole" of oxygen, O2, or TWO "moles" of O (it's important to know how you are defining your elements). …

You have 1 mole of AB_3 dissociating to produce 1 mole of A^ (3+) and color (red) (3) moles of B^ (-). You can use an ICE table to determine the value of the K_ (sp).

Nov 5, 2016 · Thus, by definition, one mole of N a2CO3XH 2O will have a mass of 106 + 18X. Given that 107.25 g of the compound is equal to 0.375 mol, then 1 mole of the compound will …

SIDE NOTE Many sources still use the old definition of STP, at which pressure is equal to 1 atm and temperature to 0∘C. Under these conditions for pressure and temperature, one mole of …

The 2:25 mole ratio that exists between the two reactants tells you that the reaction will consume 25 moles of oxygen gas for every 2 moles of octane that take part in the reaction. So, use the …

For part (b) K_(sp) = 5.3 * 10^(-6) Once again, I'll show you how to solve one example so that you can practice on the other two. A sparingly soluble salt will not dissociate completely in …

and contain 0.0025 moles of acetate ions, which were porduced by the neutralization reaction in accordance to the 1:1 mole ratio that exists between all the species involved.
