3. A gold ring has a mass of 67.0 grams. When placed in a graduated cylinder containing 10 ml of
water, the water rises to 13.47 ml. Calculate the
density of the ring.
I

The answer is

Explanation:

The density of a substance can be found by using the formula

From the question

mass = 67 g

Volume of ring = new volume of water - original volume of water

Volume = 13.47 - 10 = 3.47 mL

Substitute the values into the above formula and solve

That's

We have the final answer as

Hope this helps you

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
