Juliana is studying the effects of chemical composition on temperature change. she has a table of temperature data that were collected by a local weather station. which unit conversion is she most likely to do to use the data?

She is most likely to convert Degrees Fahrenheit (°F) to Kelvin (K) or Degrees Fahrenheit (°F) to Degrees Celsius (°C).

Scientific data must be reported using the International System of Units (SI). In that system the units used to report temperature are

A local weather station in a country that uses the imperial system such as the USA, is very likely to report temperature using Degrees Fahrenheit (°F), so Juliana would need to convert the temperatures from °F to K or °C.

To convert from °F to K:

To convert from °F to °C

Have a nice day!

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
