Answer : The moles of
are, 2.125 mole.
Explanation : Given,
Molarity of
= 8.500 M
Volume of solution = 250 mL = 0.250 L (1 L = 1000 mL)
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :

Now put all the given values in this formula, we get:


Therefore, the moles of
are, 2.125 mole.
Not 100% sure but I believe it is C.
Answer:
3.089 L
Explanation:
From the given information, provided that the no of moles and the temperature remains constant;
= 15.6 psi
= ???
= 25.43 psi
= 1.895 L
Using Boyle's law:

Answer:
2
Explanation:
because hydrogen is a diatomic element, so it can't be just H
