how many hydrogen atoms are present in 1.00mg of C14H18N2O5 (aspartame)?

Question

please show what the ratios you used in solving this

thanks soo much!

Answer 1

= (weight (g)/molecular weight) * Avogadro's number.

Answer 2

formulation for aspartame: C14H18N2O5- a million molecule aspartame includes 18 atoms H Molar mass aspartame= 294.3 g mol?a million 0.0045g = 0.0045/294.3 = a million.fifty 3*10^-5 mol No of molecules= a million.fifty 3*10^-5 * 6.022*10^23 = 9.21*10^18 No of H atoms = 9.20*10^18 * 18 = a million.sixty six*10^20 atoms

Answer 3

Find the number of moles of C14H18N2O5.

Using the periodic table, find the molecular mass of carbon, hydrogen, nitrogen, and oxygen. Multiple each elemental, molecular mass by the number in the formula and add the products together to get the molecular mass of aspartame.

Once you have the number of moles, you should know that Avogodro's number is the number of particles in a mole. Multiple the number of moles of aspartame by Avogodro's number. Then, multiple that number by 18 for the number of hydron atoms in aspartame.
