Question 1 (1 point)

Chemistry
1 answer:
EleoNora [17]3 years ago
5 0

Answer:

0.674 mol

Explanation:

Step 1:

Data obtained from the question.

Volume (V) = 4 L

Pressure (P) = 560 kPa

Temperature (T) = 127°C

Number of mole (n) =?

Step 2:

Conversion to appropriate unit.

For pressure:

101.325 KPa = 1 atm

Therefore, 560 kPa = 560/101.325 = 5.53 atm

For temperature:

Temperature (Kelvin) = temperature (celsius) + 273

temperature (celsius) = 127°C

Temperature (Kelvin) = 127°C + 273 = 400K

Step 3:

Determination of the number of mole of Neon.

The number of mole of Neon can be obtained by using the ideal gas equation as follow:

Volume (V) = 4 L

Pressure (P) = 5.53 atm

Temperature (T) = 400K

Gas constant (R) = 0.082atm.L/Kmol

Number of mole (n) =?

PV = nRT

5.53 x 4 = n x 0.082 x 400

Divide both side by 0.082 x 400

n = (5.53 x 4) /(0.082 x 400)

n = 0.674 mol

The number of mole of Neon is 0.674 mol

How many moles are in 105.7 grams of aluminum
Inessa [10]

Answer:

3.918 mol Al

Explanation:

To convert between moles and grams, you have to use the molar mass of the substance. The molar mass of aluminum is 26.98 g/mol. You use this as the unit converter.

105.7gAl *\frac{1molAl}{26.98gAl} =3.91771683molAl  

Round the number to the lowest number of significant figures; 3.918 mol Al

A proton is a subatomic particle carrying a charge equal to but opposite that of an electron
Pachacha [2.7K]

Answer:

True

Explanation:

A proton has a charge of +1, while an electron has a charge of -1. This is why a neutral atom has the same number of protons as electrons.

Neutrons have no charge, hence their name neutron which is similar to neutral.
