Molar mass sucrose:
C₁₂H₂₂O₁₁ = 342.0 g/mol
number of moles => 200 / 342.0 = 0.5847 moles
hope this helps!
At least 14 to 18 percent of water is being lost each year. I really hope this helps :D
Atomic mass Cu = 63.546 a.m.u
63.546 g ---------------- 6.02x10²³ atoms
22 g --------------------- ??
22 x (6.02x10²³ ) / 63.546 => 2.08x10²³ atoms
hope this helps!
