Make small talk and become his friend get to know him if he opens up he trust you and then you take it from there.
3*40+3*2*35.5=333* Avogadro’s number =
1.98*10^25
We first need to find the number of moles of gas in the container
PV = nRT
where;
P - pressure - 2.87 atm x 101 325 Pa/atm = 290 802.75 Pa
V - volume - 5.29 x 10⁻³ m³
n - number of moles
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 230 K
substituting these values in the equation
290 802.75 Pa x 5.29 x 10⁻³ m³ = n x 8.314 Jmol⁻¹K⁻¹ x 230 K
n = 0.804 mol
the molar mass = mass present / number of moles
molar mass of gas = 56.75 g / 0.804 mol
therefore molar mass is 70.6 g/mol
When we say COPD, this means Chronic Obstructive Pulmonary Disorder. COPD includes a group of lung diseases which have progressed into a worse condition. One example of this is emphysema. In cases of COPD, they should be provided oxygen therapy and the best flow rate for patients with this disorder is <span>8-10 L/min, high-flow, via nasal prong. Hope this helps.</span>
