Given the mass in grams , how do you find the mole (n) of a substance?, divide the mass (g) by the molar mass (g/mole), divide the molar mass (g/mole) by the mass (g), multiply the mass (g) by the molar mass (g/mole), Find the mole of the 0.52 g methanol (CH3OH). The molar mass of methanol is 32.05 g/mole. , 0.016 mole, 61.6 moles, 16.66 moles, In solving for heat given out or taken in, the equation q = mc∆T is used. What is the unit for q?, Joules , Kelvin, Celsius, To convert volume to mass, we use density. What is the density of water?, 1 g/cm3, 100g/cm3, 4.18 J/g oC, what is the mass (g) of a 20 mL water?, 20 g, 20 g/ml, 2 g, In calculating for the heat release in a reaction using the equation q = mc∆T. C is the specific heat of the substance. What is the specific heat of water , 4.18 J/g oC, 4.18 J, 4.18 J/kg.
