1. Calculate the amount of grams of CuSO4 (nice blue crystals) required to make a 0.340 M solution in a 500 ml volumetric flask. 2. When 4.05 g of CuSO4 are added to a 250 ml volumetric flask, and it is filled half way with distilled water, and gently swirled until the crystals dissolve, and then enough distilled water is added so the meniscus is right at the mark on the neck, what will be the resulting concentration of the...
O CHEMICAL REACTIONS Calculating molarity using solute moles OOOOO AUTUMN A chemist prepares a solution of zinc nitrate (Zn(NO3),) by measuring out 2.5x 10umol of zinc nitrate into a 500 ml volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's zinc nitrate solution. Round your answer to 2 significant digits. 0P x 5 ?
