1)How many grams of solid NiCl2 are needed for the following aqueous solutions? a) 250g of 3.50%(w/w) NiCl2 b) 150g of 8.20%(w/w) NiCl2 2) you have 124.8g of AgNO3 and 106.2g of BaCl2. AgNO3 is the limiting reagent. How many grams of the excess reagent will remain at the end of the reaction? Thank you
