Answer:

45.3°C

Explanation:

Step 1:

Data obtained from the question.

Initial pressure (P1) = 82KPa

Initial temperature (T1) = 26°C

Final pressure (P2) = 87.3KPa.

Final temperature (T2) =.?

Step 2:

Conversion of celsius temperature to Kelvin temperature.

This is illustrated below:

T(K) = T(°C) + 273

Initial temperature (T1) = 26°C

Initial temperature (T1) = 26°C + 273 = 299K.

Step 3:

Determination of the new temperature of the gas. This can be obtained as follow:

P1/T1 = P2/T2

82/299 = 87.3/T2

Cross multiply to express in linear form

82 x T2 = 299 x 87.3

Divide both side by 82

T2 = (299 x 87.3) /82

T2 = 318.3K

Step 4:

Conversion of 318.3K to celsius temperature. This is illustrated below:

T(°C) = T(K) – 273

T(K) = 318.3K

T(°C) = 318.3 – 273

T(°C) = 45.3°C.

Therefore, the new temperature of the gas in th tire is 45.3°C

If a sample of KF has a mass of 100.0 grams, how many moles of KF are present in the sample?
Mama L [17]

Answer:

The answer to your question is the letter b. 1.721 moles

Explanation:

Data

mass of KF = 100 g

The Number of moles = ?

Process

1.- Calculate the Molar mass of KF using the periodic table

K = 39.1

F = 19

Molar mass = 39.1 + 19

                   = 58.1 g

2.- Calculate the number of moles of KF

                      58.1 g of KF ------------------- 1 mol

                      100 g  of KF -------------------  x

                      x = (100 x 1) / 58.1

                      x = 100 / 58.1

                     x = 1.721 moles

A cube made of platinum (Pt) has an edge length of 1.0 cm. (a) Calculate the number of Pt atoms in the cube. (b) Atoms are spher
irina1246 [14]

Answer:

a)The total number of platinum atoms are 6.620\times 10^{22} atoms.

b)The radius of a Pt atom is 138.7 pm.

Explanation:

a) Let the total number of platinum atoms be x

And mass of x atoms of platinum be m

Edge length of platinum cube ,s= 1.0 cm

Volume of the cube = 1.0 cm^3

Density of the platinum cube = d=21.45 g/cm^3

Mass = Density × Volume

(m)=21.45 g/cm^3\times 1.0 cm^3=21.45 g

Mass of an atom of platinum = 3.240\times 10^{-22} g

x\times 3.240\times 10^{-22} g=21.45 g

x=6.620\times 10^{22} atoms

b) If only 74 percent of the space inside the cube is taken up by Pt atoms.

Volume occupied by platinum atoms = 74% of 1.0 cm^3

V'= 0.74 cm^3

Volume occupied by 6.620\times 10^{22} atoms is0.74 cm^3.

6.620\times 10^{22} \times \frac{4}{3}\pi r^3=V'

6.620\times 10^{22} \times \frac{4}{3}\times 3.14\times r^3=0.74 cm^3

r = 1.387\times 10^{-8} m = 138.7 pm

The radius of a Pt atom is 138.7 pm.
