Answer 1

. Molecular formula of fructose C6H12O6 Given o al molecules of be 'no. of molecules of feucrose :1.43 x102 we know that I mole of fructose consists of 6.022 X1023 molecules non of fructose er 6.022 x 10²3 molecules are there in Imole fructose Imolecule of fructose are there in - 6.022 x 1023 mole fructos 1.43 X 1024 molecule of fructose are there in 1.43x10 male fructose. 6.022 X 1023 No. of moles of fructose = - 1.438 1024 6.022 x 1023 = 1 2 = 2.375 mol & No. of moles of fructose in sample=2.375 mol | 6) Molecular formula of fructose = C6H126 no. of molecules of fructose = 1.43X 1024 mole of fructore consists of 6.022 X 1023 molecules of fructore 6.022 X 1023 molecules are there in Imole ftuchose . molecule of fructose are there in mole fructore Ics Scanned with 6.022 x 1023 CamScanner

1.43x1024 molecules of fructose are there in 1.43x10 mole fructose 6.022 x 1023 No. of make cales moles of fruchose = 2.375 moles in gives sample By looking at molecular formula, C6H12 I mole of fructose contains 6 moles of carbon 2.375 moles of fructose contains 2.375 x 6 moes of Carbon No. of moles of carbon in sample= 2.375X6 = $14.25 mole carbon c) By looking at molecular formula, 64,206 Imole of cab fructose contains 6 moles of carbon 6.23 moles of fructose contains 6. 23x6 moles of carbon No. of moles of carbon in 6.23 moles of cathen bructose - 37.38 moles No. of carbon atoms in Imole of carbon z 6.022 X 10 23. No. of carbon atoms in 37.38 mole of carbon = Scanned with 37.38x6.022x10 23-2.25 x1024 CamScanner atoms of Carbon

@ molecular formula of frucrose = Goh 1206 molar man of fructose = 6x molat mass afct 12x molar man of H+ 6x molar mass of o molare mass of fucrotez 6*12+12 x1 + 6x 16 =1809 mal Ginen mass of sample of fructose = 10.00g moles of fructose = mass of fructose molar mans of fructose moles of feuctore = 10.oogle = 10.056 mole 180 g/mol Scanned with CamScanner
