Answer:
it is Mp ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ
<u>Answer:</u> This therapy is available for 15 days.
<u>Explanation:</u>
We are given:
Oral solution dosage = 75 mg/5 mL
To calculate the volume of oral situation for single dose per, we use unitary method:
The volume required for 75 mg of solution is 5 mL
So, the volume required for 300 mg of solution will be = 
The total volume of the ranitidine bottle = 300 mL
To calculate the number of days, we divide the total volume of the bottle by the volume of dose taken per night, we get:

Hence, this therapy is available for 15 days.
Answer:
Its D Are in random motion
i hope it will help you if not soo sorry :)
Answer: This is because their valence electrons are located in the S - orbital
Explanation:
This is because their valence electrons are located in the S - orbital.
PV = nRT
R = 0.0821 L * atm / mol * K
(ideal gas constant)
First, convert 735 torr to atm. Divide by 760.
(1 atm = 760 torr)
735 torr * 1 atm / 760 torr = 0.967 atm
Then, convert 37 C to Kelvin. Just add 273.
37 C = 310K
n = PV / RT
= (0.967)(2.07) / (0.0821)(310)
= 0.0786 mol
<span>0.0786 mol * 6.02 * 10^23 molecules / 1 mol = 4.73 * 10^22 molecules </span>
