Answer:- 0.88
Solution:- Masses of silver and copper metals are given and we are asked to calculate the percentage of silver in the alloy.
mass percent of Ag = 
Mass of Ag = 17.6 g
mass of Cu = 2.40 g
mass of alloy = 17.6 g + 2.40 g = 20.0 g
Let's plug in the values in the formula:
mass percentage of Ag = 
mass percentage of Ag = 88%
So, the mass percentage of silver in sterling silver is 88% and in decimal form it is 0.88.
<span>Although Uranium (U) comes in many isotopes, Uranium has the same atomic number which is 92. The three naturally occurring isotopes of Uranium includes: U-233, U-236-, U-232. Other isotopes of Uranium are U-235 and U-238. All isotopes of Uranium comes in different atomic masses, yet, all atoms of Uranium will always be 92.</span><span />
