Answer:
Mass = 1.33 g
Explanation:
Given data:
Mass of argon required = ?
Volume of bulb = 0.745 L
Temperature and pressure = standard
Solution:
We will calculate the number of moles of argon first.
Formula:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
By putting values,
1 atm ×0.745 L = n × 0.0821 atm.L/mol.K× 273.15 K
0.745 atm. L = n × 22.43 atm.L/mol
n = 0.745 atm. L / 22.43 atm.L/mol
n = 0.0332 mol
Mass of argon:
Mass = number of moles × molar mass
Mass = 0.0332 mol × 39.95 g/mol
Mass = 1.33 g

Answer:
Tetracycline and antacid should not be given together.
Explanation:
In the given order, tetracycline and antacid are given together. The antacid is in the aspirin. The tetracycline and antacid should not be used together because the presence of antacid will suppress the effectiveness of the tetracycline. This is because antacid contains chemical compounds such as sodium bicarbonate which can interact with the tetracycline.
