How many grams are there in 6 moles of h2o?

Alexandra [31]

N= g/m therefore g=n*m so you do...
G = 6 * (Molar mass of H2O )
G = 6 * (1.01 x 2)+(16)
G = 6 * (18.02)
G = 108.12 grams of H2O

Four gases were combined in a gas cylinder with these partial pressures: 3. 5 atm N2, 2. 8 atm O2, 0. 25 atm Ar, and 0. 15 atm H

aksik [14]

The total pressure of the gas has been 11.9 atm.

The partial pressure has been the pressure exerted by the individual gas in the mixture.

According to the Dalton's law of Partial pressure, the pressure of the gas has been the sum of the partial pressure of each gas in the mixture.

<h3 /><h3>Computation for the pressure of gas</h3>

The given gas has partial pressure of Nitrogen, $P_{N_2}=3.5\;\rm atm$

The partial pressure of Oxygen, $P_{O_2}=8\;\rm atm$

The partial pressure of Argon, $P_{Ar}=0.25\;\rm atm$

The partial pressure of Helium, $P_{He}=0.15\;\rm atm$

The total pressure, (<em>P</em>) of the gas has been given as:

$P=P_{N_2}\;+\;P_{O_2}\;+\;P_{Ar}\;+\;P_{He}\\
P=3.5\;+8\;+\;0.25\;+\;0.15\;\text{atm}\\
P=11.9\;\rm atm$

The total pressure of the gas has been 11.9 atm.
