10,573.4
Explanation:
Given parameters:
Dosage per patient = 73ap/lbs
Weight of patient = 65.7kg
Unknown:
Amount of grams/ap to be given to the patient;
Solution:
Since our final answer should be expressed in grams, let us convert all units into grams.
1000g = 1kg
Converting 65.7kg to g = 65.7 x 1000 = 65700g
73ap/lbs;
1lb = 453.6g
73ap/lbs x = 0.161ap/g
Now,
For a 65700g person, the number of grains app required;
65700 x 0.161 = 10,573.4grains ap per dose

The chemical formula for oxygen is
The chemical formula for carbon dioxide is
The chemical formula for water is
Methane burns in oxygen to give carbon dioxide and water:
The balanced equation that will ensure an equal number of each atom on the left and right-hand sides of the equation would be:
6.069 grams is the mass of hydrogen formed when 27 g of aluminum reacts with excess hydrochloric acid.
Explanation:
Balanced equation for the reaction:
2 Al + 6 HCl → 2 AlCl₃ + 3 H₂
data given:
mass of aluminum = 27 grams
atomic mass of one mole of aluminum = 26.89 grams/mole
formula to calculate number of moles:
number of moles =
number of moles =
= 1.004 moles of aluminum will react
from the balanced equation:
2 moles of Al reacted to form 3 moles of H2
1.004 moles of Al will produce x moles of H2
=
x = 3.012 moles of H2 will be formed.
mass will be calculated as number of moles multiplied by atomic weight
mass of 3.012 moles of hydrogen ?(atomic weight of one mole H2 = 2.015 grams)
= 3.012 x 2.015
= 6.069 grams of H2 will be formed.
