Table salt contains 39.33 g of sodium per 100 g of salt. The US Food and Drug Administration (FDA) recommends that adults consume less than 2.40 g of sodium per day. A particular snack mix contains 1.29 g of salt per 100 g of the mix. What mass of the snack mix can you consume and still be within the FDA limit?

< 9 of 13 Review Constants Periodic Table Part A A calorimeter contains 28.0 mL of water at 11.0 °C. When 250 g of X (a substance with a molar mass of 60.0 g/mol) is added, it dissolves via the reaction X(s) + H2O(1) X(aq) and the temperature of the solution increases to 30.0 °C. Calculate the enthalpy change, AH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that...

A Review Constants Periodic Table Part A An infant's toy has a 120 g wooden animal hanging from a spring. If pulled down gently, the animal oscillates up and down with a period of 0.42 s. His older sister pulls the spring a bit more than intended. She pulls the animal 30 cm below its equilibrium position, then lets go. The animal flies upward and detaches from the spring right at the animal's equilibrium position. If the animal does not...
