How do solve for density?

1 answer:

7 0

Density(D) is defined as Mass(M) divided by Volume(V).

The formula for Density is:

D = M / V.

Another way to remember the formula for Density is to remember "Mass per unit of volume".

I hope this helps!

A 0.500 g sample of a gas has a pressure of 0.230 atm at 25.0 °C in a 0.750 L bulb. What is the molar mass of the gas?

ANTONII [103]

The molar mass of the gas is 0.04192 M.

<h3>What is molar mass?</h3>

Molar mass is the actual weight of any element or chemical compound.

The mass of the sample is 0.500 g

The pressure is 0.230

The temperature is 25.0 C

The volume is 0.750 L

Step1 – calculate the moles

$PV = nrt\\\\0.230 \times 0.750 = n \times 0.0823 \times25.0\\n = \dfrac{0.0823 \times25.0}{0.230 \times 0.750} = 11.927\;mol$

Step2 – calculate the molar mass

$\rm Molar\;mass = \dfrac{mass}{number\;of\;moles} \\\\\rm Molar\;mass = \dfrac{0.500}{11.927} =0.04192$

Thus, the molar mass of the gas is 0.04192 M.

If equal masses of nutrients are oxidized the largest amount of energy will be released by

Katen [24]

If equal masses of nutrients are oxidized, the largest amount of energy will be released by FATS.
Carbohydrates and fats are the two major nutrients that provide the energy that the cells use to carry out their biochemical activities, but the amount of energy that is obtainable from fat is much more greater than that of carbohydrates.
