When 85 L of gas at 1.376 atm has its pressure changed to 0.154 atm, what is the new volume?
igor_vitrenko [27]

Answer:

<h2>759.48 L</h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{85 \times 1.376}{0.154}  =  \frac{116.96}{0.154}  \\  = 759.480519...

We have the final answer as

<h3>759.48 L</h3>

Hope this helps you

11.1 ml sample of Neon Gas is at a pressure of 811 torr What volume will
yarga [219]

Answer:

C.106 ml

Explanation:

Boyle's Law P₁V₁ = P₂V₂ , but we need to make sure our pressure is in the same units, in this case we will convert torr to atm

811 torr * (1atm/760torr) = 1.067105263 atm

P₁V₁ = P₂V₂

(1.067105263 atm)(11.1 mL) = (0.112 atm)(V₂)

V₂ = 11.84486842/0.112

V₂ = 105.7577538 mL = 106 mL

A wooden block has a length of 4.0 cm, a width of 2.0 cm, and a height of 1.0 cm. What is the volume of this block?
MakcuM [25]
Use the formula for volume. V = lwh. Plug in the numbers for length, width, and height. Now we have V = 4.0 x 2.0 x 1.0, which is 8.0. So the volume of the block is 8.0 cm.
