".
Explanation:
calculating the moles in
Eqution:

Calculating the amount of
produced:

So, the amount of dihydrogen produced = 
Answer:
4.4 mol.
Explanation:
Hello!
In this case, since the formula for calculating the molarity is:

Whereas n stands for moles and V for the volume in liters; we can solve for n as shown below when we are given the volume and the molarity:

Thus, we plug in the given data to obtain:

Best regards!
Answer:

Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the required new volume by using the Charles' law as a directly proportional relationship between temperature and volume:

In such a way, we solve for V2 and plug in V1, T1 and T2 to obtain:

Answer:
Potassium permanganate has a molar mass of 158.04 g/mol. This figure is obtained by adding the individual molar masses of <em><u>four oxygen atoms</u></em>, <em><u>one manganese atom</u></em> and <em><u>one potassium atom</u></em>
