Please make sure the answer is in the correct sigfigs! Suppose 6.34 g of lead(II) acetate is dissolved in 300. mL of a 0.40 Maqueous solution of ammonium sulfate. Calculate the final molarity of lead(II) cation in the solution. You can assume the volume of the solution doesn't change when the lead(II) acetate is dissolved in it. Be sure your answer has the correct number of significant digits. x 6 ?

I have the correct answers but don't know how to solve these correctly? The naturally occurring charge on the ground on a fine day out in the open country is 2.59 nC. What is the electric potential at a height of 3.83 m? Correct Answer: 6.079 In open heart surgery, a much smaller amount of energy will defibrillate the heart. Heart defibrillators store 35 J of energy and the voltage is applied to a 7 μFcapacitor. Find the amount of...
with correct ammount of sigfigs please 1 attempts left Check my work Enter your answer in the provided box. The enthalpy of combustion of benzoic acid (CH,COOH) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be -3226.7 kJ/mol. When 3.0081 g of benzoic acid are burned in a calorimeter, the temperature rises from 20.84°C to 25.67°C. What is the heat capacity of the bomb? (Assume that the quantity of water...
help me to solve problem 1 and 2. I really apreciate your help 1) Find -x.y). and use the total differential to approximate the quantity (2.01)2 (8.02) 22.3.
