AT constant temperature, a gas is compressed from 5.5 L to 1 L. At 1 L, the pressure of the gas is 98.2 kPa. What was the origin

svet-max [94.6K]

We have that the original pressure of this gas is mathematically given as

P2=17.854 kPa

<h3>Boyle's law</h3>

Question Parameters:

AT constant temperature, a gas is compressed from 5.5 L to 1 L.

At 1 L, the pressure of the gas is 98.2 kPa

Generally the equation for Boyle's law is mathematically given as

P1V1=P2V2

Therefore

$P1=\frac{P2V2}{V1}\\\\P2=\frac{98.2*1}{5.5}$

P2=17.854 kPa

1.572x108 Troy oz of silver were used in the us in 1980 how many kilograms is this

Anna71 [15]

Answer: 4873200 kg

Explanation:

Given mass: $1.572\times 10^8$ troy oz

Conversion factor : $1troyoz=0.031kg$

Thus if 1 troy oz weighs in kg = 0.031 kg

$1.572\times 10^8$ troy oz will weigh in kg = $\frac{0.031}{1}\times 1.572\times 10^8=0.04873\times 10^8kg$

Thus there are $0.04873\times 10^8kg$ in $1.572\times 10^8$ troy oz of silver used.
