What is the mass, in kilograms, of 3.28 x 103 mol of H2O?

Answers

3.28 x 10³ mol of water has a mass of 59.1156 kg. This is the accurate answer to the given question.

How do you determine 3.28 x 10³ mol of H2O's mass in kilograms?

We can use the molar mass of water, which is 18.02 g/mol, to calculate the mass of 3.28 x 10³ moles of H2O. The following equation can be used to translate the quantity of moles into grams:

mass is determined by multiplying the number of moles by the molar mass.

Inputting the values provided yields:

18.02 g/mol times 3.28 x 10 3 moles of mass equals 59,115.6 g.

Lastly, by dividing by 1000, we can change the mass from grams to kilograms:

mass is 59,115.6 grams per kilogram (59.1156 kg).

As a result, 3.28 x 10³ moles of H2O have a mass of 59.1156 kg.

What is the volume of a tank of nitrogen if it contains 17 moles of nitrogen at 34 C under 12,000 Pa?

Answers

Answer: 3571 L

Explanation:

According to the ideal gas equation:'

$PV=nRT$

P = Pressure of the gas = 12000 Pa = 0.12 atm $1Pa=9.9* 10^(-6)atm$

V= Volume of the gas = volume of tank = ?

T= Temperature of the gas = 34°C = 307 K $0^0C=273K$

R= Gas constant = 0.0821 atmL/K mol

n= moles of gas= 17

$V=(nRT)/(P)=(17* 0.0821* 307)/(0.12)=3571 L$

Therefore Volume of tank is 3571 Liters.
