Answer:
35.0 kPa
Explanation:
As pressure decreases, the volume of a gas increases at a given temperature., so since the balloon got bigger, the new pressure must be less than 103kPa
Assuming the temperature does not change, use Boyles Law
P1V1 = P2V2
(103kPa) (1750L) = P2 (5150L)
P2 = (103)(1750) / 5150
You're going to use the PV= nRT formula. You'll add 273 to 25 to get the temperature in K and you'll plug in everything you know
Into the formula. You also must change Liters into milliliters, so it will be 1200 ml. After putting everything into the formula you can solve it algebraically. The moles of gas would be about 540.19
Answer:
in 6.0 E3 g of blood at a concentration of 0.62 ppm there are 3.5g of lead content
Explanation:
- blood density: 1.06 g/L
- ppm ≡ mg Pb / L blood
⇒ V blood = 6.0E3gblood * L / 1.06gblood = 5660.37 L blood
<u> mass of lead:</u>
⇒ 5660.37 L blood * 0.62 mg Pb / L blood * 0.001 g / mg
⇒ mass = 3.509 g of lead

Answer: The new volume of the gas is smaller.
Explanation:
Volume and pressure are inversely proportional (as one goes up, one goes down). So as you increase the pressure, you decrease the volume.
