Question

U dle preselil ill 2.30 Mules Ul llapices b. How many moles of H are present in 0.444 mole of naproxene?

Answer 1

Ans b

Chemical formula for naproxene = C14H14O3

Moles of naproxene = 0.444 mol

From the chemical formula 1 mol naproxene contains 14 mol H

Moles of H in naproxene = 0.444 mol x 14

= 6.216 mol

Ans 5

Part a

Mass of Ag = 82.0 g

Moles of Ag = mass/molecular weight

= (82g) / (107.8682 g/mol)

= 0.760 mol

Part b

Mass of C = 0.288 g

Moles of C = mass/molecular weight

= (0.288 g) / (12 g/mol)

= 0.0240 mol
