Hi, I'm having a lot of trouble with what these questions are asking. If anyone could help with any or all I would greatly appreciate it! 3NO2 + H2O = 2HNO3 + NO How many grams of HNO3 can be produced from the reaction of 3.00 moles of NO2? 2AgNO3 + Cu = Cu(NO3)2 + 2Ag How many grams of AgNO3 are needed to produce 0.523 grams of Ag? Thank you!
