A sample of damp air in a 1.00 L container exerts a total pressure of 741.0 torr at 20 oC; but when it is cooled to -10 oC, the
AlexFokin [52]

From the information presented in the question, the number of molecules present of water present is obtained 2.41 × 10^21 molecules.

From the information we have;

Volume of the damp air =  1 L

Pressure of the damp air =  741.0 torr or 0.975 atm

Temperature of the gas = 20 oC + 273 = 293 K

R = 0.082 atm LK-1mol-1

Number of moles = ?

n =PV/RT

n = 0.975 × 1/0.082 ×  293

n = 0.041 moles

Volume of water vapor = 1 L

Temperature of water = -10 oC + 273 = 263 K

Pressure of the gas = 607.1 torr or 0.799 atm

R = 0.082 atm LK-1mol-1

n= PV/RT

n = 0.799 × 1/ 0.082 × 263

n = 0.037 moles

Number of moles of water = 0.041 moles -  0.037 moles = 0.004 moles

If 1 mole = 6.02 × 10^23 molecules

0.004 moles = 0.004 moles × 6.02 × 10^23 molecules/1 mole

= 2.41 × 10^21 molecules

given a density of 350 grams/cm3 and a mass of 25 grams. What is the volume using the equation involving density?​
Eduardwww [97]

0.07cm³

Explanation:

Given parameters:

Density of the body = 350g/cm³

Mass of the body = 25g

Unknown:

Volume of the body = ?

Solution:

Density is the amount of substance contained in a volume of body. It is expressed as:

    Density = \frac{mass}{volume}

Since the unknown is volume, we make it the subject of the expression;

   Volume = \frac{mass}{density}

 Volume = \frac{25}{350} = 0.07cm³

sergeinik [125]
<span>The type of map that shows the type and age of rocks in an area is called a Geologic Map. A geologic map is a special-purpose map that represents the distribution of diverse types of rocks, as well as locations of different geologic structures such as faults and folds. This map is the main source of information for various aspects of land-use planning, especially in the placement of transportation systems and buildings. Although they are typically depicted as two-dimensional, they can also be illustrated in its third or fourth dimension depending on the type of information needed to be taken. </span>
