What is the average atomic mass of the element?

morpeh [17]

The average atomic mass of element X is 14.007 u.

The average atomic mass of X is the weighted average of the atomic masses of its isotopes.

We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its % abundance).

Thus,

0.996 36 × 14.003 u =13.952 03 u

0.003 64 × 15.000 u = 0.054 60 u

__________TOTAL = 14.007 u

How many grams of a solution that is 5.2% sucrose by mass are needed to obtain 18g of sucrose

kirill115 [55]

Answer:

346.g of solution

Explanation:

In this case, if we have 5.2 % by mass it means that in 100 g of the solution we will have 5.2 g of glucose. Therefore we can do the calculation:

5.2 g of glucose = 100 g of solution

$18~g~of~glucose\frac{100~g~of~solution}{5.2~g~of~glucose}=346.15~g~of~solution$

So, if we need 8 g of glucose we had to have 346.15 g of solution

This logic can work for all types of solutions. By mass (as in this case), by volume or mass/volume.

I hope it helps!
