1.	48. A glass of juice contains 9 g of glucose. The number ofcarbon atoms in the glass of juice is(1 1.8069 x10 (2) 1.5012 x 10*(3) 2.5012 x 10 4)
Answer» 1 mol of C6H12O6= 180 g = 6.0210^23molecules 9 g = ? Number of molecules in 9 g of C6H12O6 = 96.0210^23/ 180 = 3.0110^22molecules Number of C atoms in 9 g of glucose = 63.0110^22= 18.06 * 10^22atoms very very very thanks

48. A glass of juice contains 9 g of glucose. The number ofcarbon atoms in the glass of juice is(1 1.8069 x10 (2) 1.5012 x 10*(3) 2.5012 x 10 4)

Answer»

1 mol of C6H12O6= 180 g = 6.02*10^23molecules 9 g = ?

Number of molecules in 9 g of C6H12O6 = 9*6.02*10^23/ 180 = 3.01*10^22molecules

Number of C atoms in 9 g of glucose = 6*3.01*10^22= 18.06 * 10^22atoms

very very very thanks
