What is the empirical formula for a substance if a 201.6 g sample of it contains 54.0 grams of nitrogen, 15.0 grams of hydrogen,
jeyben [28]

The empirical formula of the substance would be  NH_4Cl

<h3>Empirical formula calculation</h3>

The constituents of the compound are as follows:

N = 54/201.6 = 26.78% = 26.78/14 = 1.91 moles

H = 15/201.6 = 7.44% = 7.44/1 = 7.44 moles

Cl = 132.6/201.6 = 65.48% = 65.48/35.5 = 1.84 moles

Divide the number of moles by the smallest"

N = 1.91/1.84 = 1

H = 7.44/1.84 = 4

Cl = 1.84/1.84 = 1

Thus, the empirical formula is NH_4Cl

When copper metal is affed to silver nitrate in solution, silver metal and copper (II) nitrate are produced. Use the balanced eq
trapecia [35]
<h2>Answer:</h2>
  • Cu(s) + 2AgNO3(aq) → Cu(NO3)2(aq) + 2Ag(s).

<u>Moles Cu present</u> = 100g Cu x 1 mol Cu/63.55g

= 1.574moles Cu

<u>Mass of Ag produced</u> = 1.574mol Cu x 2mol Ag / 1mol Cu x 107.9g Ag/mol Ag

= 340.g Ag
