Answer: The mass percent of hydrogen in ascorbic acid is 4.5 %
Explanation:
In 
, there are 6 carbon atoms, 8 hydrogen atoms and 6 oxygen atoms.
To calculate the mass percent of element in a given compound, we use the formula:
Mass of hydrogen = 
Molar Mass of ascorbic acid =
Putting values in above equation, we get:
Hence, the mass percent of of hydrogen in ascorbic acid is 4.5 %.
Answer:
drought
Explanation:
droughts are long periods without water
.4 M means that in 1 Liter of solution there are .4 moles.
Molarity x Liters = Moles
We have molarity, so convert mL to liters
250 mL x 1000mL/1 Liter = .25 L
Now, set up the equation
.4 M x .25 L = .1 moles of solute
Answer:
It is composed of 57.17% S and 42.83% C and has a molar mass of 448.70 g/mol. Determine the empirical and molecular formulas of “sulflower.”
