1. 14 g of salt dissolves in 250cm3 of distilled water give a concentration of 0.80 moldm-3 calculate the salt
2. What mass of k2 cr2 O4 is required to prepare 250cm3 of 0.020 moldm-3 solution ( k² - cr4=194.2 g mol-1)
3. What volume of 0.05 moldm-3 H2SOH in cm³ will exactly neutralize 20cm³ 0.1mold-3 NaoH solution
4. A solution is prepare by dissolving 196g of H2 SO in 250cm³ of its solution. What is the concentration in moldm-3
5. 20cm³ of a solution containing 0.58g of any hydrous Na2 Co3 in 100cm³ required 25cm³ of H2 So4 for complete neutralization. The concentration in Moldm-3?
