A sample of gas has a volume of 526 mL at 346 mmHg and 35.0°C. Determine the moles of gas.​
Furkat [3]

Answer:

The moles of gas is 0.009474 moles.

Explanation:

Given that,

Volume = 526 mL

Pressure = 346 mmHg

Temperature = 35.0°C

We need to calculate the moles of gas

Using formula of ideal gas

n=\dfrac{PV}{RT}

Where, P = pressure

V = volume

R = gas constant

T = temperature

Put the value into the formula

n=\dfrac{\dfrac{346}{760}\times0.526}{0.08206\times(35+273)}

n=0.009474\ moles

Hence, The moles of gas is 0.009474 moles.

The rate law for the reaction NH4(aq)+ + NO2(aq)- → H2O(l) + NO2(g) is rate = k [NH4+][NO2-], and the value of k is 2.7*10-4 M-1
dybincka [34]
We are given the rate law, so we can substitute the given values for the rate constant and the concentrations of the reactants to solve for the rate of reaction. Since rate = k [NH4+][NO2-]:
rate = (2.7 x 10^-4 / M-s)(0.050 M)(0.25 M) = 3.375 x 10^-6 M/s
