How many 1/3 cups do you need to make 1/2 cup? - Socratic
Oct 23, 2016 · one and a half 1/3 cups make 1/2 cup We need to figure out how much more than 1/3 cup is 1/2 cup. That translates to this equation: 1/3+x=1/2 if we subtract 1/3 from both sides we get: x=1/2-1/3 In order to subtract or add fractions we need to make the denominators (the bottom parts) of both fractions equal to each other. In order to do that we find the Least …

Nuclear Half-Life Calculations - Chemistry - Socratic
Where Th = half-life. M. = the beginning amount M = the ending amount. One example of how to use the equation: One of the Nuclides in spent nuclear fuel is U-234, an alpha emitter with a half-life of 2.44 x10^5 years. If a spent fuel assembly contains 5.60 kg of U-234, how long would it take for the amount of U-234 to decay to 0.35?
How many feet are in 1/2 of a mile? - Socratic
Mar 6, 2018 · See a solution process below: We know the conversion factor of miles to feet is: 1" mile" = 5280" feet" To find how many feet in a 1/2 mile we can multiply each side of the equation by color(red)(1/2) giving: color(red)(1/2) xx 1" mile" = color(red)(1/2) xx 5280" feet" 1/2" mile" = 5280/2" feet" 1/2" mile" = 2640" feet" There are 2,640 feet in 1/2 mile
The "pH" at one-half the equivalence point in an acid-base …
Mar 9, 2018 · K_a = 2.1 * 10^(-6) The idea here is that at the half equivalence point, the "pH" of the solution will be equal to the "p"K_a of the weak acid. Assuming that you're titrating a weak monoprotic acid "HA" with a strong base that I'll represent as "OH"^(-), you know that at the equivalence point, the strong base will completely neutralize the weak ...
