Answer:
The molarity is 0,35M
Explanation:
The molartity is moles of compound in 1 liter of solution :
20 L----------7moles compound
1 L..-----------x= (1L x7 moles compound )/20L= 0,35 moles compound--> 0,35M
I believe the answer is two
Given:
Temperature = T, unknown
Saturated Solution, NH4Cl concentration = 60g/100g H2O = 0.6g NH4Cl/g H2O
Assume density of H2O = 1 g/ml
m = 0.6g NH4Cl/g H2O / 1 g/ml
m = 0.6g NH4Cl/ml
See the table of saturated solutions and identify the temperature at which the concentration of NH4Cl is 60g/100g H2O. <span />
