A sample of sulfur dioxide (SO2) is initially at a temperature of
creativ13 [48]

Answer:

874.89 mmHg

Explanation:

Using the combined gas law equation as follows:

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (mmHg)

P2 = final pressure (mmHg)

V1 = initial volume (L)

V2 = final volume (L)

T1 = initial temperature (K)

T2 = final temperature (K)

Based on the information provided in this question;

P1 = 950 mm Hg

P2 = ?

V1 = 25 L

V2 = 30 L

T1 = 155°C = 155 + 273 = 428K

T2 = 200°C = 200 + 273 = 473K

Using P1V1/T1 = P2V2/T2

950 × 25/428 = P2 × 30/473

23750/428 = 30P2/473

55.49 = 0.063P2

P2 = 55.49 ÷ 0.063

P2 = 874.89 mmHg

Cassie buys a rope at the store. The label on the package says that the rope is 3.15 meters in length. She measures the rope as
satela [25.4K]

Answer:

Percent error = 41%

Explanation:

Percent error:

Percent error is the difference between the measured value and actual value divided by actual value multiply by 100.

Given data:

Actual length of rope = 3.15 m

Measured length of rope = 1.85 m

Percent error = ?

Solution:

Formula:

Percent error = [measured value - actual value / actual value ] × 100

Now we will put the values in formula.

Percent error = [1.85 - 3.15 / 3.15 ] × 100

Percent error = [-1.3 /3.15 ] × 100

Percent error = -0.41 × 100

Percent error = 41%

The negative sign shows that measured value is less than the actual value but often results are reported in absolute value.
