A sample of gas has a mass of 0.0707 grams and has a volume of 48.9 milliliters. What is the density of this gas?
GREYUIT [131]

The density of the gas is 1.45 g/L.

The mass of the gas is 0.0707 g.

The volume of the gas is 48.9 mL.

Density = mass/volume = 0.0707 g/48.9 mL = 1.45 × 10⁻³ g/mL = 1.45 g/L

The air pressure in a tire is 2.38 atm. What is the pressure in kilopascals.
Anna71 [15]

Answer:

The answer is

<h2>241.15 kPa</h2>

Explanation:

To find the pressure in kilopascals we must first find the pressure in Pascal

To find the pressure in Pascal we use the conversion

1 atm = 101 , 325 Pa

If 1 atm = 101325 Pa

then 2.38 atm = 2.38 × 101325

= 241153.5 Pa

Converting it into kPa we have the final answer as

<h3>241.15 kPa</h3>

Hope this helps you
