Answer:

The tank with O₂ weighs more.

Explanation:

We can find the mass of gas using the ideal gas equation.

P.V=n.R.T=\frac{m}{M} .R.T\\m=\frac{P.V.M}{R.T}

Considering the pressure (P), volume (V), temperature (T) and ideal gas constant (R) are the same, we can establish that:

m ∝ M

The mass is directly proportional to the molar mass. The molar mass of O₂ (32 g/mol) is higher than the molar mass of N₂ (28 g/mol). Therefore, the tank with O₂ weighs more.

= 1.5ml/dose X 4 doses/daily X 10 days = 60 ml

<h3>What do you know about amoxicillin?</h3>

Numerous bacterial infections can be treated with amoxicillin. This drug is an antibiotic similar to penicillin. It acts by preventing bacterial development. Only bacterial illnesses are treated by this antibiotic. For viral infections, it is ineffective (such as common cold, flu). Any antibiotic that is overused may stop working to treat subsequent illnesses. Along with other drugs, amoxicillin is also used to treat and prevent the recurrence of stomach / intestinal ulcers brought on by the bacteria H. pylori. Take this medication by mouth every 8 to 12 hours, generally with or without food, as prescribed by your doctor. Your medical condition and treatment response will determine the dosage.
