What is the molar mass of a substance in amu converted to kg/mol?

To convert the molar mass of a substance from atomic mass units (amu) to kilograms per mole (kg/mol), you need to multiply the molar mass in amu by the conversion factor 1.66054 x 10-27 kg/amu. This will give you the molar mass in kg/mol.


How many 450 mg in pounds?

To convert milligrams to pounds, divide by 453592. There are approximately 0.000992 pounds in 450 milligrams.


What is the same as a single copper atom 1.055 x 10 -22g in kg?

The mass of a single copper atom is incredibly small but can be calculated. In this case, 1.055 x 10^-22g is equal to 1.055 x 10^-25 kg when converted from grams to kilograms.


A nurse must administer to her patient 5mg of a drug per kg of body mass the patient weighs 140lbs how many grams should she give?

350mg I believe the way to do the problem is divide the 140 by 2.2 (since 1lb = 2.2kg), that should give you 63.6363...kg You then have to convert the 5mg to g which would be 0.005g. You must then multiply 63.6363...kg by 0.005g which equals 0.3181815g = 0.32g. 140lb/2.2kg = 63.6363 5mg = 0.005g 63.6363kg x 0.005g = 0.3181815g = 0.32g I hope this helps, it took me awhile to figure out some sort of equation as well. In fact I hope my calculations are correct also lol, it worked out on the calculator.


How Many Litres of LPG equals 1 Cubic Meter?

Conversion factor depends on various factors like composition of the LPG, temperature, molecular weight and so many others.Following are the conversion factors just for rough calculations.One kg of liquid Propane when converted to vapour (at 15.56 degrees centigrade temperature) will be equal to 0.539 Cubic Meter.One kg of liquid Butane when converted to vapour (at 15.5 degrees centigrade temperature) will be equal to 0.410 Cubic Meter.One kg of liquid LPG (70:30) when converted to vapour (at 15.5 degrees centigrade temperature) will be equal to 0.449 Cubic Meter.OR45kg LPG = 20.20 Cu. Meter vapour. Or for 45kg Propane = 24.26 Cu. Meter of vapour.As a thumb rule Liquid Propane expands to 270 times and Butane to 235 times into vapour when released into air.
