a 500 ml portion of .0020 M Na2C2O4 solution is able to dissolve .47g of MgC2O4. What is the Ksp for MgC2O4
Can anyone help me get some points? What can the Church do today to make itself more relevant to Generation X?
The length of the base of a triangle is 4 times its altitude. If the area the triangle is 162 cm2, find the altitude.
PartA: What volume of 10.0M NaOH is needed to prepare a buffer with a pH of 7.79 using 31.52 g of TrisHCl? TrisHCl is a weak base and the molecular weight is 157.67 g/mol. I found the solution, it is 6.67 milliliters. The main question is:Part B: "The buffer from Part A i...
45.00 mL of 1.55×10^−2 M HI(aq) is mixed with 85.00 mL of 1.08×10^−2 M KOH(aq). What is the pH of the solution?
What is [H3O+] in a solution obtained by dissolving 215 mL HCl(g), measured at 23 degrees C and 757 mmHg, in 4.30 L of aqueous solution?
can u tell me what your final answer is? I got 7.96 * 10 ^5 ml.
How many millimeters of this solution should be diluted with water to produce 650 mL of a solution with pH= 11.50? 6.8% ammonia (d= 0.97g/ml)
I thought for the density, the calculation would be as follows: 0.15gKOH/g---> 1g of solution, density=1.14 g/ml.......0.15g/(1g/1.14g/ml) to get 0.171 g/ml. and then I thought molarity for [OH^-] was 2.51 * 10^-3. The proper set up I got like 3.66 g/? mL. I might be wrong!...
