Answer to Question #133381 in General Chemistry for Mike

Question

How much moles of carbon contain in 0,15 mol sucrose?

Count the mass of water which is dissolved 250g sucrose will make up 55% sucrose solution?

How much grams of water required to pour into 150 cm3 syrup (density of syrup=1,258g/cm3 and procentive concentration 55%) to get the procentive concentration of sucrose 25%?

How much grams of water required to evaporate from 150cm3 syrup (density of syrup = 1,258g/cm3 and procentive concentration 55%) to get the procentive concentration of sucrose 65%?

Technician accidently made 0,150L solution in which sucrose molar concetration was 3,00 mol/L. Suggest a way how we could fix this mistake from already made solution (molar concentration 2,03 mol/l)?
