In a can of soda (335 grams of soda ) there are 33g of sugar. What is the mass percent of sugar in soda?

9.85% is the mass percent

Explanation:

Mass percent can be determined as mass of solute in 100 g of solution

The solution is soda

Sugar is the solute

(mass of solute / total mass of solution) . 100 =

(33 g / 335g) . 100 = 9.85%

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.
