Answer:
You can calculate joules by calculating the kinetic energy, or energy of motion, of an object. You can also calculate the joules by calculating the amount of work accomplished by a person or machine. Lastly, you can calculate joules by converting directly from a measurement in calories
N2 is a diatomic molecule as it is composed of 2 atoms of the same element, covalently bonded to each other in this case Nitrogen.
Answer:
Explanation:
Given data:
A) Moles of H₂O₂ = 7.00
Mass of H₂O₂ = ?
Solution:
Number of moles = mass/ molar mass
Now we will rearrange this formula:
Mass = Number of moles × molar mass
Mass = 7.00 mol × 34 g/mol
Mass = 238 g
B) Moles of NaOH = 5.60 mol
Mass of NaOH = ?
Solution:
Number of moles = mass/ molar mass
Now we will rearrange this formula:
Mass = Number of moles × molar mass
Mass = 5.60 mol × 40 g/mol
Mass = 224 g
C) Moles of Ca(CN)₂ = 0.780
Mass of Ca(CN)₂ = ?
Solution:
Number of moles = mass/ molar mass
Now we will rearrange this formula:
Mass = Number of moles × molar mass
Mass = 0.780 mol × 92.11 g/mol
Mass = 71.85 g
The answer to this question is 6.25ml
To answer this question, you need to calculate the azithromycin drug doses for this patient. The calculation would be: 25kg * 10mg/kg/d= 250mg/d
Then multiply the doses with the available drug. It would be:
250 mg/d / (200mg/5ml)= 6.25ml/d
