A ball of iron weighs 55.265 g and measures 3.00 cm in diameter. What is the density of the iron ball? (V= -ar', where r is the radius)
The mass unit associated with density is usually grams. If the volume (in mLmL or cm3cm3) is multiplied by the density (g/mLg/mL or g/cm3g/cm3) the volume units will cancel out, leaving only the mass units. Keep in mind that the volume and density must use the same volume unit for the cancellation. If a large marshmallow has a volume of 3.00 in3in3 and density of 0.242 g/cm3g/cm3, how much would it weigh in grams? 1 in3=16.39 cm31 in3=16.39 cm3.
Suppose that a new temperature scale has been devised on which the melting point of ethanol (-117.3°C) and the boiling point of ethanol (78.3°C) are taken as 0°S and 100°S, respectively, where S is the symbol for the new temperature scale. Derive an equation relating a reading on this scale to a reading on the Celsius scale. What would this thermometer read at 25°C?
The mass of a beaker is 5.333 g. After 5.00 mL of a concentated hydrochloric acid solution is pipet Ted into the beaker, the combined mass of the beaker and the hydrochloric acid sample is 11.229 g. From the data, what is the measured density of the hydrochloric acid solution?
