Answer:

2.5 Times . 10–3 L.

Explanation:

1 L = 1000 mL

1 mL = 1×10⁻³ L

2.5 mL / 1000 = 2.5×10⁻³ L

2.5 mL . 1×10⁻³ = 2.5×10⁻³ L

Answer:

A. 2.5 Times. 10–3 L.

Explanation:

In conversion from milliliters (ml) to liters (l), the formular is to; divide the volume value by 1000.

Given Volume (mL) = 2.5

Volume in L = mL / 1000 = 2.5 / 1000

Volume in L = 2.5 *  10^{-3}

A sample of neon gas occupies 105 L at 27°C under a pressure of
Viefleur [7K]

Answer: Volume occupied by given neon sample at standard condition is 123.84 L.

Explanation:

Given: V_{1} = 105 L,    T_{1} = 27^{o}C = (27 + 273) K = 300 K,     P_{1} = 985 torr

At standard conditions,

T_{2} = 273 K,     P_{2} = 760 K,        V_{2} = ?

Formula used to calculate the volume is as follows.

\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}

Substitute the values into above formula as follows.

\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}\\\frac{985 torr \times 105 L}{300 K} = \frac{760 torr \times V_{2}}{273 K}\\V_{2} = \frac{94116.75}{760} L\\= 123.84 L

Thus, we can conclude that volume occupied by given neon sample at standard condition is 123.84 L.

Allergies arise when a foreign material such as pollen, bee venom or pet dander responds to your immune system or a food that in most people does not cause a reaction. Substances known as antibodies are formed by your immune system.
