Question

If you have 22.42 grams of HC1, how many grams of MnCl2

Answer 1

`232.14\text{ grams}`

Step-by-step explanation:

Here, we want to get the mass of manganese chloride

We start by getting the number of moles of HCl

Mathematically:

`number\text{ of moles = }\frac{mass}{molar\text{ mass}}\text{ = }(22.42)/(36.46)\text{ = 0.615 mol}`

From the information given, 1 mole of Hcl produces 3 moles of MnCl2

Thus, the number of moles of MnCl2 produced will be:

`0.615\text{ }*\text{ 3 = 1.84 mol}`

Finally, to get the mass, we multiply the above number of moles by the molar mass of MnCl2

Mathematically, we have that as:

`1.84\text{ }*\text{ 125.84 = 232.14 grams}`
