A quantity of ice at 0 degree C is added to 64.3g of water in a glass at 55 degree C. After the ice melted, the temperature of the water was 15 degree C. How much ice was added? The heat of fusion of water is 6.01 kJ/mol and the specific heat is 4.18J(g*C). can someone explain this in detail. other descriptions don't answer this well and im lost when i try and do it

a 10.00g sample of toothpaste contaning stannous fluoride gives0.145g precipitate of stannous phosphate.what is the percentage of snf2 in the toothpast sample.
Rank the following compounds in order of reactivity toward nitration with HNO3
the equivalence point i know you need to use [A-]= moles of HA/(vol water added+vol NaOH added) and believe moles of HA=5.39x10^-3
The value of Kf for cyclohexane is 20.0°C/m, and its normal freezing point is 6.6°C. A mass of 1.604 g of a waxy solid dissolved in 10.000 g of cyclohexane results in a freezing point of 4.4°C. Calculate the molar mass of the solid.
