"A mineral is a homogeneous (which means composed of parts or elements that are all of the same kind) naturally occurring substance with a definite but not necessarily fixed chemical composition. Most minerals are solids with an ordered atomic arrangement, and most are inorganic in the chemical sense of that word".

1. Find the density of an object that has a mass of 8.2 grams and a volume of 3 cc.

satela [25.4K]

The actual formula for volume for a cube is the length multiplied by the width and then multiplied by the height. Since all three measurements are the same, the formula results in the measurement of one side cubed. For the example, 5^3 is 125 cm^3. Multiply the volume by the known density, which is the mass per volume.

If a bag of peas weighs 454 grams, how many peas would be in the bag?

OverLord2011 [107]

In a bag of peas that weighs 454 grams, there are between 1261 and 4540 peas.

The average pea weighs between 0.1 and 0.36 grams.

If we take the lower value (0.1 g/pea), the number of peas in 454 g is:

$454 g \times \frac{1pea}{0.1 g} = 4540pea$

If we take the higher value (0.36 g/pea), the number of peas in 454 g is:

$454 g \times \frac{1pea}{0.36 g} \approx 1261pea$

In a bag of peas that weighs 454 grams, there are between 1261 and 4540 peas.

An unknown sample weighing 0.3512g was added to 20.0 mL of cyclohexane. The density of cyclohexane is 0.779g/mL, and the freezin

rjkz [21]

Explanation:

It is known that density is mass of a substance divided by its volume.

Mathematically, Density = $\frac{mass}{volume}$

Therefore, calculate the mass of cyclohexane as follows.

mass of cyclohexane = Density × volume

= $0.779 g/mL \times 20 mL$

= 15.58 g

or, = 0.01558 kg (as 1 kg = 1000 g)

As, K_{f} of cyclohexane = $20^{o}C/m$

$\Delta T_{f} = K_{f} \times molality$

$5.2 = 20 \times molality$

molality = $\frac{5.2}{20}$

= 0.26 m

Also, molality is the number of moles of solute present in kg of solvent.

Mathematically, molality = $\frac{\text{no. of moles}}{\text{mass of solvent}}$

0.26 = $\frac{\text{no. of moles}}{0.01558}$

No. of moles = $4.05 \times 10^{-3}$

As, No. of moles = $\frac{mass}{\frac{molar mass}}$

$4.05 \times 10^{-3} = \frac{0.3512}{\text{molar mass}}$

molar mass = 87.0 g/mol

Thus, we can conclude that molar mass of unknown substance is 87.0 g/mole.
