Molecular formula of Isoflurane is <span><span>C</span></span>₃H₂ClF₅O.
Now calculate
the percent composition by mass, which means percent of each element in the
compound.
Mass of Isoflurane
= 184.49 g/mol
Mass of carbon in the compound = 3 x
12.011 = 36.033g
Mass of hydrogen in the compound = 2 x
1.008 = 2.016g
Mass of chlorine in the compound = 1 x 35.453
= 35.453 g
Mass of fluorine in the compound = 5 x 18.998
= 94.99g
Mass of Oxygen in the compound = 1 x 16
= 16 g
Carbon’s percentage = Mass of carbon in
the compound /mass of isoflurane x 100 =36.033/184.49 x 100 =19.53%
Hydrogen’s Percentage = Mass of hydrogen
in the compound/mass of isoflurane x 100 = 2.016/184.49 = 1.09%
Chlorine’s percentage = Mass of chlorine
in the compound/mass of isoflurane x 100 = 35.453/184.49 =19.22%
Flourine’s percentage = Mass of fluorine
in the compound/mass of isoflurane x 100 = 94.99/184.49 x 100 = 51.49%
Oxygen’s percentage = Mass of Oxygen in
the compound/mass of isoflurane x 100 =16/184.49 x 100 = 8.67%

one US ton is 2000 lbs, thus 2/5 of that is just their product.
answer: 800 lbs
The question is incomplete.
The complete question probably is
The pH scale for acidity is defined by pH = − log₁₀[H⁺] where [H⁺] is the concentration of hydrogen ions measured in moles per liter (M). A solution has a pH of 2.55. Find the hydrogen ion concentration.
Answer: -
0.003 M
Explanation: -
pH = − log₁₀[H⁺]
Thus the hydrogen ion concentration [H⁺] = 
= 
= 0.003 M
According the VSEPR theory the molecular geometry for CH3+ is triagonal planar
Answer:Why does weathering cause erosion
Explanation:Organic weathering happens when plants break up rocks with their growing roots or plant acids help dissolve rock. Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity.
