<span>First set up the equation 39.33g/100g = x/1.28g and that'll give you how much sodium is in each 100g of the mix.
39.33g *1.28g= 100g * x
x = 0.503424g
x = Amount of sodium per 100g of the mix
Now 2.4g / 0.503424 = 4.7674
Multiply by 100 and you get 476.7353g</span>

DNA, which is found in chromosomes in the nucleus
For every mole of any substance or element, the total number of atoms is 6.022 x 10^23. This is called the avogadro's number. Hence, for a) for a 0.90 mole copper, the number of atoms is 5.42 x10^23. This also applies for B) which gives silver as given. For c), the number of molecules present in a compound is also the same. Thus, for a,b,and c, the answer is 5.42 x10^23.
