Answer: 2 grams
Explanation:
chemical formula of C6H:
C6H
relative atomic mass of
C:12
H:1
C6:72
H1:12
relative formula mass of
C6H1=73
molar mass of glucose:
73g
the molar mass is the mass of one mole of a substance.
in
26.2g
of C6H there are
26.2 divide by 73g moles present.
there are 0.358 or 35.8*10-1
I gram of NH3 is 17.03052
2 grams of NH3 is 35
To compute the percent error, you divide the absolute difference between the actual value and the measured value with the actual value. Then, multiply it with 100 to get the percentage. The solution is as follows:
Percent error = (250 - 243.9)/250 * 100
Percent error = 2.44%
The answer is that compounds are formed when elements are joined and held together by strong forces called chemical bonds.Covalent bonds share electrons between atoms in order to fill their electron shells. In the compound, molecules are held together by the attraction between the nucleus and the shared electrons. (I got this from the internet so credits to the internet)
The number of protons and electrons of an atom is equal
and the amount can be obtained by looking at the atomic number of that atom or
element.
The atomic numbers are:
Gold = 79
Thallium = 81
So we are looking for the element with an atomic number of
80, that is:
Mercury

Answer : The volume of solution will be 2.96 liters.
Explanation :
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
In this question, the solute is NaF.
Now put all the given values in this formula, we get:
Therefore, the volume of solution will be 2.96 liters.
