First find the number of moles of KSCN is in 4.40g of KSCN
1. Number of moles = mass given (4.40g) / molecular weight(MW) (KSCN)
- to calculate MW, look for each element in the periodic table and add their atomic weight
2. Convert 200mL to liters
3. Concentration = number of moles/ volume in liters from (#2)
Answer:
