Density of water in gcm32/26/2024 ![]() ![]() x = 27.917 cm 3 (However, when performing further calculations use 27.9173 keeping in mind that the last significant digit is the second 7. So, if 0.99753 g of water occupies 1 mL, then 27.8474 g of wateroccupy what volume? Things to watch out for Combining Mathematical operations/order of operations.Įxact numbers (definitions, things that can be counted, the 1 in numbers like 19.6 g/cm 3)įrom the density of water we know that 1 cm 3 weighs0.99753 g, or you could say 0.99753 g water occupies 1cm 3. multiplication/division the result of multiplying two numbers should have the same number of significant figures as the number with the fewest significant figures. addition/subtraction the result of adding two numbers together should be precise to the place that corresponds to the least precise measurementī. ![]() ![]() The density of the reference substance is usually water at a specified temperature, often 4☌ or 20☌. Determining the number of significant figures that shouldremain after performing mathematical manipulations with thenumbers. Yes, you can convert specific gravity to density using the formula: Density (g/cm³) Specific Gravity x Density of Reference Substance. in 0.0560 the leading zeros are not significant, but the trailing zero is.Ģ. (note) This density is at 0 ☌ temperature and 101.325 kPa pressure. they occur after a non-zero number in a number whose absolute value is < 1. Density of all elements in g/cm 3 is mentioned in the chart below. they occur before and after the decimal point of a number whose absolute value is > 1 e.g. Determining thenumber of significant figures in a measurement. Wood is another material that floats on water since. Should I use 1.00 g/cm 3 as the density? No, use thedensity of water at the temperature of the experiment should be used.At 23.0 ☌ the density of water is 0.99753 g/cm 3.ġ. Cork floats on water because it has a very low density of about 0.2 g/cm3. ![]() The rationale: if I know the mass of the water in the flask I caneasily convert it to the volume of the water. At 23.0 ☌ the density ofwater is 0.99753 g/cm 3įill with water, stopper, wipe, and weigh flaskĭetermine the volume of the flask using the density of water You can effortlessly find every single detail about the elements from this single Interactive Periodic table.Significant Figures and the Determination of theVolume of a Picnometer (the flask)ĭetermine the volume of a flask. Let me tell you how this Interactive Periodic Table will help you in your studies.ġ). (note) This density is at 0 ☌ temperature and 101.325 kPa pressure 87 Francium (Fr) no data 88 Radium (Ra) 5 g/cm 3 89 Actinium (Ac) 10.07 g/cm 3 90 Thorium (Th) 11.725 g/cm 3 91 Protactinium (Pa) 15.37 g/cm 3 92 Uranium (U) 19.05 g/cm 3 93 Neptunium (Np) 20.45 g/cm 3 94 Plutonium (Pu) 19.82 g/cm 3 95 Americium (Am) 13.67 g/cm 3 96 Curium (Cm) 13.51 g/cm 3 97 Berkelium (Bk) 14.79 g/cm 3 98 Californium (Cf) 15.1 g/cm 3 99 Einsteinium (Es) no data 100 Fermium (Fm) no data 101 Mendelevium (Md) no data 102 Nobelium (No) no data 103 Lawrencium (Lr) no data 104 Rutherfordium (Rf) no data 105 Dubnium (Db) no data 106 Seaborgium (Sg) no data 107 Bohrium (Bh) no data 108 Hassium (Hs) no data 109 Meitnerium (Mt) no data 110 Darmstadtium (Ds) no data 111 Roentgenium (Rg) no data 112 Copernicium (Cn) no data 113 Nihonium (Nh) no data 114 Flerovium (Fl) no data 115 Moscovium (Mc) no data 116 Livermorium (Lv) no data 117 Tennessine (Ts) no data 118 Oganesson (Og) no data Free Gift for you: Interactive Periodic Table ![]()
