Need on some homework questions i’m stuck on about molarity and dilutions:
1. how many moles of c12h22o11 (sucrose) are in 7.5 l of a 5.8 m c12h22o11 solution?
2. how many moles of solute licl are in 375 grams of an 85.0 percent by mass solution?
3. how many grams of copper metal will react completely with 4.50 l of 6.00 m hcl?
cu (s) + 2hcl (i) -> cucl2 +h2 (g)
4. completely describe how to make 3.5 l of a 2.0 m nacl solution from a stock solution of 6.0 m nacl.
5. how many grams of a stock solution that is 90.0% hcl by mass would be needed to make 175 grams of a 40.0% hcl by mass solution?
6. how many grams of silver metal would you expect to be produced when 250. grams of an 80.0% by mass silver nitrate solution reacts with excess copper metal?
cu (s) 2agno3 (aq) -> 2ag (s) + cu(no3)2 (aq)
you so much and try to answer all of the questions.
