98 grams of potassium chloride are added to 217 grams of water. the volume of the water is 200 cm3. when the water reaches saturation, the undissolved salt is removed. if potassium chloride has a solubility of 95 g/dm3, what is the mass of the final solution?

Electrons are extremely important to what area of technology? a) anti-aging research b) household product development c) electronics d) drug discovery

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
