Explain how you can make 200ml of 1.0M Copper sulfate solution and then dilute 50mL of that solution to make a 0.2M solution using Copper sulfate pentahydrate (molar mass 250g)

Asample of aluminum foil contains 8.60 × 1023 atoms. what is the mass of the foil?

The vapor pressure of water at 25.0°c is 23.8 torr. determine the mass of glucose (molar mass = 180 g/mol) needed to add to 500.0 g of water to change the vapor pressure to 22.8 torr.

Tinererining 01: 57: 44 which statement correcte describes the actual veld and the theoretical yield of a reaction? textual vec is calculated to the reactant amounts but the theoretical yeld must be measured for each instance of a the actual vec is calculated from the amount of the limiting reactant and the theoretical yield is calculated from the 发公主 the actual weld depends on the reaction centers, but the theoretical yield and only with reactant amounts the actual vele represents the maximum weld possible and the theoretical yield assumes perfect reaction conditions save and ext e அட
