117.0 14
93.0 21
23.3 63

Part 1: What is the half-life of the element? Explained how you determined this.

Part 2: How long would it take 320 g of the sample to decay to 2.5 grams? Show your work or explain your answer.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

have a great day because if you dont you and i will be sad

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
