Answer:
C
Explanation:
Since they all are 2 mols worth, all you have to do is count the number of atoms in each molecule
H2SO4 contains 2 hydrogen 1 sulfur 4 oxygen = 7 atoms
H2S contains 2 hydrogen and 1 sulfur = 3 atoms
H3PO4 contains 3 hydrogens 1 phosphorus 4 oxygens = 8 atoms
HNO3 contains 1 hydrogen 1 nitrogen and 3 oxygens = 5 atoms
You have the right answer.
Molybdenum Arsenide
I think that’s right but not %100 sure
Explanation:
It is known that density is the amount of mass present in liter of solution or substance.
Mathematically, Density =
It is given that volume is 3.25 L and mass is . Hence, calculate the density of glycerol as follows.
Density =
=
=
As, 1 L = 1000 .
So,
=
Thus, we can conclude that the density of glycerol is .
Answer:
The concentration of nitrate ion is 0.033 M.
Explanation:
1 mole of = 3 mole
Let = 3y
then according to above reaction,
= y
= 0.10 M (given)
= ?
3y = 0.10 M
y = 0.033 M
So ,concentration of = y = 0.033 M
