What is the mass percentage of carbon in 5.000 g of sucrose? 50.00 g of sucrose? 500.0 g of sucrose? Explain.

first you have to know the molecular formula of carbon which is C12H22O11, Then with that you can calculate the mass of each element in the molecule. C:12.01*12= 144.12, H: 1.008*22= 22.176, O: 16*11= 176

Explanation: give me brainliest pls

chemistry sucks a**

explanation:

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.
