Calculate the effective radiation dosage (in Sieverts) for a 85-kg person who is exposed to 7.3 × 109 particles of alpha radiation. Assume that 85% of the radiation is absorbed, each alpha particle has an energy of 6.0× 10-13 J, and that the RBE of the alpha particles is 15. Note that RBE is sometimes abbreviated as Q.
Calculate the molality of ions in a solution made by mixing 5.14 g of CaCl2, MW=110.98, in 79.38 mL of water at 37.0°C. The density of water at this temperature is 0.9933 g/cm3. The answer is 1.76m but I don't know how to get there.
