Answer:

The correct answer is d. 4.7 atm

Explanation:

We apply Boyle Mariotte's law, where for a certain mass of gas at constant temperature, the pressure and temperature vary inversely proportionally: P1xV1 = P2xV2

P2= (P1xV1)/V2= (1,0 atm x 4,0 L)/0,85L= <em>4, 705882353 atm</em>

43. A stock glucose standard has a concentration of 1,000 mg/dL. A 1/5 dilution of this standard is made. What would be the fina
Nat2105 [25]

The final concentration of the diluted standard is 0.2 mg/dL.

<h3 /><h3>What is concentration of glucose standard after 1/5 solution?</h3>

Using the dilution formula:

  • C1V1 = C2V2

where

  • C1 is initial concentration
  • V1 initial volume
  • C2 is final concentration
  • V2 is final volume.

Assuming a final volume of 100 mL, and since a 1/5 dilution is made:

C1 = 1.00 mg/dL

V1 = 20

C2 = ?

V2 = 100 mL

C2 = C1V1/V2

C2 = 20 × 1/100

C2 = 0.2 mg/dL

Therefore, the final concentration of the diluted standard is 0.2 mg/dL.
