required to be older

A gas system has an initial number of moles of 0.693 moles with the volume unknown. When the number of moles changes to 0.928 moles volume is found to be 7.98 L. What was the initial volume in mL?

Answers

Answer:

The initial volume in mL is 5959.2 mL

Explanation:

As the number of moles of a gas increases, the volume also increases.  Hence, number of moles and volumes are directly proportional i.e

n ∝ V

Where n is the number of moles and V is the volume

Then, n = cV

c is the proportionality constant

∴n/V = c

Hence n₁/V₁ = n₂/V₂

Where n₁ is the initial number of moles

V₁ is the initial volume

n₂ is the final number of moles

and V₂ is the final volume.

From the question,

n₁ = 0.693 moles

V₁ = ?

n₂ = 0.928 moles

V₂ = 7.98 L

Putting the values into the equation

n₁/V₁ = n₂/V₂

0.693 / V₁ = 0.928 / 7.98

Cross multiply

∴ 0.928V₁ = 0.693 × 7.98  

0.928V₁ = 5.53014

V₁ = 5.53014/0.928

V₁ = 5.9592 L

To convert to mL, multiply by 1000

∴ V₁ = 5.9592 × 1000 mL

V₁ = 5959.2 mL

Hence, the initial volume in mL is 5959.2 mL

ACT Read the passage from "The Salem (and Other) Witch Hunts, which is an informational text about witch hunts in the late 1600s.The sentencing of Bridget Bishop, the first victim of the witch trials, was typical of the Salem justice. Bishop was accused of not living "a Puritan lifestyle" because she wore black clothing. Her coat had been found to be oddly "cut or torn in two ways, and her behavior was regarded as "immoral. Thus convicted of witchcraft, she was tried on June 10, 1692, and executed by hanging the same day.Immediately following this execution, the court adjourned for 20 days and asked for advice from New England's most influential ministers "upon the state of things as they then stood. A mere five days later, they produced a voluble answer penned by Cotton Mather, the prolific pamphleteer of the period, assuring the court and the grand jury that they had done well.The prominent ministers "humbly recommend[ed]" more of the same: that is, "the speedy and vigorous prosecution of such as have rendered themselves obnoxious, according to the direction given in the laws of God, and the wholesome statutes of the English nation . . . More people were accused, arrested and examined, but historians believe that by September 1692 the hysteria had begun to abate and public opinion turned against the trials.Which text structure supports the idea that the sentencing was swift and the hysteria surrounding the witch hunts was relatively short-lived?sequencecomparison-contrastcause-effectproblem-solution Marshall Welding Company has two service departments (Cafeteria and Human Resources) and two production departments (Machining and Assembly).
