Exposure to arsenic can result to subacute to severe toxicity and can sometimes be lethal and cause death. One source of arsenic is from agricultural runoffs. The concentration of arsenic in an agricultural wastewater is determined gravimetrically. A 25.0000 g sample of wastewater was precipitated as MGNH,AsO, and isolated as Mg,As,O7. Determine the %w/w_ of As,O, in the sample if it yields 1.5610 of Mg,As,O7.

Sodium hydrogen carbonate (NAHCO,), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI) , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: 圖 HCl(aq) + NaHCO,(aq) → NaCl(aq) + H,O(1) + CO,(g) ol. The CO, gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be 250. mL of a 0.065 M HCl solution. What mass of NaHCO, would she need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits.
