A student is told to use 20.0 g of sodium chloride to make an aqueous solution that has a concentration of 10.0 g/L (grams of sodium chloride per liter of solution). Assuming that 20.0 g of sodium chloride has a volume of 7.50 mL, show that she will need about 1.99 L of water to make this solution. In making this solution, should she add the solute to the solvent or the solvent to the solute?

How would you measure the density of rock candy, which is irregularly shaped and water soluble?
Hello,
I am having an issue with figuring the following: For pH 9.5 I am getting 3.16 x 10 ^-10. Is this correct? Thank you
Solution X has a pH of 9.5, and solution Y has a pH of 7.6.?
What is [H3O+] in Solution X?
What is [H3O+] in Solution Y?
The acidity or alkalinity of a solution is defined by
pH = –log[H+] where [H+] is the hydrogen ion concentration, measured in moles per liter.
Solutions with a pH value of less than 7 are acidic; solutions with a pH value of greater than 7 are basic and solutions with a pH of 7 (such as pure water) are neutral.
a) Suppose that you test apple juice and find that the hydrogen ion concentration is [H+] = 0.0003. Find the pH value and determine whether the juice is basic or acidic.
