41) A teenage child in Wisconsin throws a chunk of sodium metal into a lake consisting of freshwater with an number of fluorine. A tremendous explosion follows emitting light and heat able t approximate density of 1.01 g/mL. The chunk of sodium has a mass (in kilograms) equal to the atomic be observed from a drone flying at an altitude of approximately_53 m. How many atoms of sodium from the original chunk remain in Wisconsin after the reaction is complete? This is an MCAT style question. Keep in mind that some of the data given may nột be necessary to solve the problem. Use four sig figs. 1.01g/mL 53 ら3m a) 4.616E25 b) 2.357E23 2.853E26 c)
