To find molarity use the following formula
molarity= moles/ liters
first, we need to calculate the moles using the grams of NH₃. remember to convert grams to moles, you need the molar mass of the molecule which you can determine by adding the mass of each atom
molar mass of NH₃ = 14.0 + (3 x 1.01)= 17.03 g/ mol
now, let convert grams to moles
17.0 g (1 mol/ 17.03 grams)= .998 moles NH₃
now, we can plug in these values to solve for molarity
molarity= 0.998 mol/ 2.0 Liters= 0.50 M (the answer is a)
Answer:
yes!you are right a cloudy formation will be formed when they will react.its because if nitrogen.
Answer:
Final Volume = 5.18 Liters
Explanation:
Initial Condition:
P1 = 789 mm Hg x (1/760) atm /mm Hg = 1.038 atm
T1 = 22° C = 273 + 22 = 295 K
V1 = 4.7 L
Final Condition:
P2 = 755 mm Hg x (1/760) atm /mm Hg = 0.99 atm
T2 = 37° C = 273 + 37 = 310 K
V2 = ?
Since, (P1 x V1) / T1 = (P2 x V2) / T2,
Therefore,
⇒ (1.038)(4.7) / 295 = (0.99)(V2) / 310
⇒ V2 = 5.18 L (Final Volume)
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
