Question- Calculate the concentration (in M) of 8.395 g of AgNO3 (molar mass = 169.9 g/mol) dissolved in 125 mL of water. Give your answer to three significant figures
Can anyone tell me how to solve it step by step?
Suppose 12.0 g of carbon (C) reacts with 65.0g of sulfur (S) to give 76.0 g of the compound carbon disulfide (CS2). In the process, all the carbon gets used up, but some elemental sulfur is left over. For the law of conservation of matter to b..
