Answer:
Coefficient = 1.58
Exponent = - 5
Explanation:
pH = 2.95
Molar concentration = 0.0796M
Ka = [H+]^2 / [HA]
Ka = [H+]^2 / 0.0796
Therefore ;
[H+] = 10^-2.95
[H+] = 0.0011220 = 1.122 × 10^-3
Ka = [H+] / molar concentration
Ka = [1.122 × 10^-3]^2 / 0.0796
Ka = (1.258884 × 10^-6) / 0.0796
Ka = 15.815 × 10^-6
Ka = 1.58 × 10^-5
Coefficient = 1.58
Exponent = - 5
N = given mass/ molar mass.
n = number of moles
given mass = 2.47 g
molar mass = 197 g/mol
n = 2.47 / 197
n = 0.01253 moles.
I'm sure you wanted to ask more than this. Just put some comments in. I can do the same.
Answer:
Solar power
Or in some cases, from heat from the sun. ... Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels that are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity.
Explanation:
According to the question:
Given,
= 250mg 75mg 375mg
= 5Cc X 250 X
= X = 1.5ml
= 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.
