This is a fundamental SI unit and is denoted as N A. The number is equal to 6.02214076×10 23 and is known as Avogadro’s constant. The law states that equal volumes of gases under equal temperature and pressure will contain the same number of molecules.Īvogadro’s number is named in his honor. he is most famous for proposing Avogadro’s law. Lorenzo Romano Amedeo Carlo Avogadro was an Italian scientist. This concept is used extensively across organic, inorganic, and physical chemistry. Thus mole is a fundamental quantity when chemical calculations are involved. The atomic mass of one mole of an element, molecular compound or ionic compound is known as the Gram formula mass (a.k.a. 6.023 x 10 23 number of molecules or atoms (depending on the type of compound it is) is present in one mole of a substance. Weight of one mole of an element, ionic compound or molecular compound is the Gram formula mass. So, the conversion factor to multiply by to convert from lb/in 3 to lb/ft 3 is 1728.2 Solved Examples for Gram Formula Mass Gram Formula Mass Dividing both sides of the equation by 5.787037e-04 we get 1728 lb/ft 3 = 1 lb/in 3. Knowing that 1 lb/ft 3 = 5.787037e-04 lb/in 3 we can now find the conversion factor for converting back. Since you can multiply anything by 1 and still retain the original value, but in different units, set it up so that ft 3 will cancel out leaving you with in 3.ġ lb/ft 3 = 1 lb/ft 3 * (1 ft / 12 in) 3 = 1 lb/ft 3 * (1 ft 3 / 1728 in 3) = 5.787037e-04 lb/in 3Īnd we now have our factor for conversion from lb/ft 3 to lb/in 3 since 1 * 5.787037e-04 = 5.787037e-04. Say you want to convert from lb/ft 3 to lb/in 3.
To understand how to also convert the units follow this example. So, to convert directly from lb/ft 3 to g/mL you multiply by 0.016018463.
Or, you can find the single factor you need by dividing the A factor by the B factor.įor example, to convert from lb/ft 3 to g/mL you would multiply by 16.018463 then divide by 1000. To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into kg/m 3 then divide by the factor for B to convert out of kg/m 3. To convert from kg/m 3 into units in the left columnĭivide by the value in the right column or, multiply by the reciprocal, 1/x.Ĩ00.92315 kg/m 3 / 16.018463 = 50 lb/ft 3 Multiply by the value in the right column in the table below.ĥ0 lb/ft 3 * 16.018463 = 800.92315 kg/m 3 To simply convert from any unit into kg/m 3, for example, from 50 lb/ft 3, just Where S is our starting value, C is our conversion factor, and By knowing the conversion factor, converting between units can become a simple multiplication problem: Convert among mass density values along with mass concentration values (mass divided by volume).Īvoirdupois system, the standard everyday system in the United States where 1 ounce = 1/16 poundĬonversions are performed by using a conversion factor.
