Please help with question 2 a-c Topic 7
1. Give the name and calculate the molar mass for each of the following substances. a. HNO₂ b. MgSO4.7H₂O C. CoCl₂ 2. Calculate the mass in grams of each of the following samples. a. 25.5 x 1024 nitrogen molecules b. 9.301 moles of Sulfuric Acid c. 3.20 x10¹ moles of Ferric Bicarbonate 3. Calculate the percent by mass of the second element in the properly written formula. Example, for Ferric Hydroxide, the % would be based on the Oxygen from the formula Fe(OH)3 (do not rely on google for your nomenclature since that kept giving FeHO₂, an incorrect formula for the name given.) a. Calcium Acetate b. Ammonium Sulfate c. Iron (II) Nitrate 4. 72 molecules of a compound has a mass of 1.82x10-20g. The molar mass of this compound is? (hint, molar mass is defined as grams/mole) 5. What mass of solute is necessary to prepare a 500mL flask of 0.100M NaOH solution? ||| <
