If there are 8.24 x 1022 molecules of NaCl in a salt shaker, what is the mass of the salt? What is the molality (mol) of a 2.0 M solution of NaCl and distilled water when the solution is 50 mL and solute is 5.85 g NaCl? What mass of sodium chloride solute is needed to make 15...
The density of the substance is the ratio between a specified mass of that substance and its corresponding volume. The density of a mass will work for any mass with a corresponding volume since density is specific to the substance in consideration. Densities have no unique unit ...
What mass (in grams) of KCl is required to make 60 mL of a 0.20 M KCl solution? If I need to dissolve 25.0 g of compound A in 50.0 mL of water, what is the mass % of my solution? Density of water = 1.00 g/mL What mass of KBr ...
Molar mass is the number of grams of a substance that equals one mole or6.02x1023molecules, also known as Avogadro's number. Molar mass can be used to convert between moles and grams, denoted byg/mol. Answer and Explanation: KMnO4

Potassium is a mineral that helps maintain the water and acid balance in blood and tissue cells, assists in muscle building, and transmits electrical signals between cells and nerves. Symptoms of hypokalemia, or potassium deficiency, include dry skin, muscle weakness, fatigue, and slow reflexes....
In \(1880\), Van’t Hoff introduced a factor (i) to account for the extent of dissociation or association of solute particles in a solution. The factor (i) is known as the Van’t Hoff factor, which is defined as: \(\text {i}=\frac{\text { Normal Molar Mass }}{\text { Abnorm...
