Answer:
The volume of sample at STP is = 41.22 ml
Explanation:
Given data
= 0.9 atm
= 50 ml
= 298 K
At STP
= 1 atm
= 273 K
From ideal gas equation
= 41.22 ml
Therefore the volume of sample at STP is = 41.22 ml
Acetylene has a chemical formula which can be written as:
C2H2
We can see that there are two positive ions, H+. Now what
deprotonation means is that the H+ is removed from acetylene to form acetylene
ion and water. In this case, I believe that the answer would be:

Molarity of a solution is the molar concentration, which is the number of moles of solute in 1 L of solution.
the mass of glucose is - 125 g
number of moles of glucose - 125 g / 180.16 g/mol = 0.694 mol
the number of moles of glucose in 650.0 x 10⁻³ L - 0.694 mol
number of moles of glucose in 1 L - 0.694 mol / 650.0 x 10⁻³ L = 1.068 mol/L
molarity of glucose solution is 1.068 M

Answer:
The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance (the decimal associated with percent of atoms of that element that are of a given isotopе). An element does not have an absolute atomic mass.
