<h3>Answer:</h3>
6278 mmHg
<h3>
Explanation:</h3>
Kilopascal (kPa) and Millimeter of Mercury (mm Hg) are both the units of Pressure. In medical science the pressure is often measured in mm of Hg.
Also,
0.133322387415 kPa equals = 1 mmHg equals
Then,
837 kpa will be equal to = X mmHg
Solving for X,
X = (837 kPa × 1 mmHg) ÷ 0.133322387415 kPa
X = 6278.0153898 mmHg
Or when rounded to 4 significant numbers,
X = 6278 mmHg
Molarity is defined as the number of moles of solute in 1 L of solution
number of moles of NaI - 10.7 g / 150 g/mol = 0.0713 mol
there are 0.0713 mol in 0.250 L
we need to find the number of NaI moles in 1 L
if 0.250 L contains - 0.0713 mol
then 1 L contains - 0.0713 mol / 0.250 L = 0.285 mol/L
molarity is 0.285 M
Be more specific, I could possibly find the asnwer you're looking towards.
Answer:
D. A north pole and south pole attract each other
Answer:
final concentration: Ca = 0.014 M
Explanation:
Velocity of reaction:
∴ α: order of reaction, assuming α = 1
∴ K = 0.249 s-1.......rate constant
∴ Cao = 0.050 M......initial concentration
∴ t = 5 s.......reaction time
⇒ δCa/δt = K*Ca
⇒ ∫δCa/Ca = K*∫δt
⇒ Ln(Cao/Ca) = K*t = (0.249s-1)(5 s) = 1.245
⇒ Cao/Ca = 3.473
⇒ Ca = 0.050/3.473
⇒ Ca = 0.014 M
