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.
how many significant figures would my answer have if i devide 94.997grams/10mL?
Suppose you are trying to find the volume of a box based on the given measurements for the length, width and height of the box, where the height was measured in two parts. length, 7 = 2.20 in width, w = 3.71 in height, h = 10.4 in + 1 in Calculate the height, h, of the box, first keeping all digits, then rounding to the proper number of significant figures. Calculate the volume (v) of the box using ?=?×?×ℎ. Round to the proper number of significant figure.
Straight-chain, saturated carboxylic acids, a class of hydrocarbons, have the general formula CnH2n+1COOH where n is an integer that ranges from 1 to 18. What would be the %C by mass if n = 8? Atomic weights: C = 12.01, H = 1.01, O = 15.99. Input values only with two decimal places. Do not include the units.
If mercury (density = 13.6 g/cm3) at a height of 895 mm Hg in a mercury barometer is replaced with water (density = 1.00 g/cm3), under the same conditions the height of water will be. (The unit of your answer should be in meter with five significant figures)
