You are working out on the treadmill machine at the gym. the machine says that you are burning 110 calories per mile (110 calories = 1.0 mile). how many miles would you have to run to burn 500.0 calories?

So 500/110=4.54545455, so 4.54545455 rounded to the nearest hundredth is 4.55 miles!

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.
