A can of coke contains 25 mL of carbon dioxide gas at 100kPa. If you take it on a hike up Mount Everest and the pressure decreas

Mazyrski [523]

Answer:

50 mL

Explanation:

We can solve this problem by using Boyle's Law, which states that:

"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"

Mathematically:

$p\propto \frac{1}{V}$

where

p is the pressure of the gas

V is the volume of the gas

The equation can be rewritten as

$p_1 V_1 = p_2 V_2$

where in this problem:

$p_1 = 100 kPa$ is the initial pressure of the gas in the coke

$V_1=25 mL$ is the initial volume

$p_2=50 kPa$ is the final pressure

Solving for V2, we find the final volume:

$V_2=\frac{p_1 V_1}{p_2}=\frac{(100)(25)}{50}=50 mL$

A chemical manufacturer sells sulfuric acid in bulk at a price of $100 per unit. If the daily production cost in dollars for x u

sleet_krkn [62]

to solve the amount of sulfuric acid to maximize the profit we need to establish the profit

let S(x) = 100x the selling price

P = S(x) – C(x)

P = 100x – ( 100,000 + 50x + 0.0025x^2)

P = 50x – 100000 – 0.0025x^2

Getting the first derivative and equating it to 0

0 = 50 – 0.005x

X = 10000 units of sulfuric acid

But the capacity is only 7000 units

<span>So 7000 units should be manufactured</span>
