Question

A compound is discovered and its molecular weight is determined to be 526g/mol. however, one of the elements has not yet been identified. what is the missing element, x, in batio9(x7)?

Answer 1

Sulphur

The missing element is sulphur

Here the compound is composed of  element X and chlorine.

it is given,

XCl (6) ----> 6Cl

mass = 13.1%

it is X and Cl = 100%-13.10%

                     = 86.90%

chlorine = 86.90            

X = 13.10

We assume 100g of sample

so according to the above solved data, in 100g of sample we have 86.90 g of chlorine.

now we split that chlorine into two moles of chlorine.

• Every mole of sale has 35.45 grams of sales. 2.451 moles of seal are mine after that.
• We are aware that cl is six times more than X. To find the moles of X, I must divide this number by six.
• we discover that we have  0.4086 moles of X when we divide this by six.
• We obtain those moles of X from 13.10 g of X.  
• Given that Mueller masses grams per mole, I can compute the molar mass.
• 13.10 grams of X are contained in 0.4086 moles of X.
• Or, to put it another way, each remote has a molar mass of 32–06 grams.
• The element with this molar mass is sulfur, as I can see from the periodic table.
• Okay, so the element we're looking for in this situation is sulfur.
