Answer:
(a).molar mass=(12×9)+(1×8)+(16×4)
=180.0g
(b).moles of Aspirin
moles=mass(g)÷molar mass
=360.4÷180.0
=2.002moles
(c). molecules of Aspirin
To get molecules just multiply moles of Aspirin by Avocado number.
=2.002×6.022×10^23
=1.206×10^24 molecules
(d) number of carbon atoms
=12×9
=108 carbon
Answer:
In the backrest use materials where it is easy to clean and where they do not absorb fluids, in this way it would be cooler, such as an ecological leather simulator.
And in the armrest as well, but in both areas we must not rule out that if or if it should have even a minimum of padded surface so that the patient or the person who spends most of the day in the wheelchair does not suffer from joint pain.
Explanation:
Some wheelchair factories also implement modern chairs where they are made of stainless steel structures lined with padded material with perforated fabrics that allow breathing and aeration of body areas that have contact with the fabric.
Answer:
I believe its false
Explanation:
a carrying capacity is the maximum amount of living things that can be held in a single container
Answer: 20.7 kJ
Explanation:
According to first law of thermodynamics:
=Change in internal energy
q = heat absorbed or released
w = work done or by the system
w = work done on the system=
{Work is done on the system is positive as the final volume is lesser than initial volume}
w = 4.51 kcal = 
(1kcal = 4.184kJ)
q = +1.79 kJ {Heat absorbed by the system is positive}
Thus for a system that receives 1.79 kJ of heat from surroundings and has 4.51 kcal of work done on it at the same time is 20.7 kJ
