Question

If there are 0.4 moles of SeCI6 how many grams do you have. Use up to one decimal point

Answer 1

`116.8\text{ g}`

Step-by-step explanation:

Here, we want to get the mass of the given number of moles

To get this, we can use the mathematical formula below:

`mass\text{ = number of moles }*\text{ molar mass}`

The number of moles is 0.4 mol

The molar mass of SeCl6 is 292 g/mol

Thus, we have the mass as:

`mass\text{ = 0.4 }*\text{ 292 = 116.8 g}`
