We know the formula of the density:
ρ =
;
So the mass will be equal to:
m = ρ * V = 2.70 * 21.3 = 57,51 g =
57510 mg of substance.
So the answer is 57510.
The products for the complete combustion of a hydrocarbon in excess air is carbon dioxide and water. Any hydrocarbon when reacted with oxygen will always yield the said products. Incomplete combustion, on the other hand, yields carbon monoxide and water.
Which formula represents a molecule with the most polar
bond? (1) CO (3) HI (2) NO (4) HCl
The formula that represents a molecule with the most
polar bond is the HCl, hydrochloric acid. The answer is number 4.
Answer: The hydrogen ion concentration in molarity is 0.013
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pOH is calculated by taking negative logarithm of hydroxide ion concentration and pH is calculated by taking negative logarithm of hydrogen ion concentration
Putting in the values:
Now ,
The hydrogen ion concentration in molarity is 0.013
