Molar Mass: The molar mass, or molecular weight, of a substance, is the mass in grams contained within one mole of its particles. These particles are atoms, molecules, or ions. An example is the methane molecule {eq}\rm CH_4 {/eq}, which has a molar mass of {eq}\rm 16.0 ...
What is the molar solubility (in {eq}\rm mol/L {/eq}) of {eq}\rm AgCl\ (K_{sp} =1.44 \times 10^{-16}) {/eq} in a {eq}\rm 0.10\ M\ AgNO_3 {/eq} solution? Molar Solubility: Molar solubility refers to the totality of moles in a ...
What is the boiling point of a solution (in degrees Celsius) that was prepared by dissolving 13.38 grams of MgCl2 in 250.0 grams of water? What is the boiling point change for a solution containing 0.736 moles of naphthalene, a non...
Answer to: A solution of H2SO4(aq) with a molal concentration of 2.55 m has a density of 1.151 g/mL. What is the molar concentration of this...
1. Homework Statement In a calorimeter, a 1.0g sample of magnesium is burned to form MgO. In doing so, 25.5 kJ of energy is released. The molar enthalpy of combustion of magnesium is: a) -0.0392 kJ/mol b) -25.5 kL/mol c) -306.2 kJ/mol d) -620 kJ/mol Homework Equations Q= mc...
Mg is a metal forms a cation with +2 ox Ionic compound with cris-cross: MgCl2 Given different pairs of atoms, how would you decide which has the most polar bond? I would first deal with covalent vs ionic Non-metals with nonmetals = covalent Metals with non-metals = ionic If I was ...

Explanation : You start any question of this type by writing a balanced equation for the reaction : MgO(s) + 2HCl (aq) → MgCl2(aq) + H2O(l) This tel..
What is the molality of ethanol in an aqueous solution that is 48.2% ethanol by mass? Solutions: The concentration of a solution can be expressed in different units in which different considerations are made. As an example, for mass percent, the concentration can be expres...
What kind of crystalline solid is MgCl2?Crystal Structure of Ionic Solids:The crystal structures of ionic solids are based on the geometry of the unit cell. A unit cell is the simplest repeating structure of a crystalline solid. There are seven categories of unit cell configurations: cubic, ...
