Crown b is made of solid gold
Anit [1.1K]3 years ago

Answer:

If I'm not mistaken crown b is pure gold

Explanation:

If the crown was made of pure gold, the two volumes would be equal. If some other (less dense) metal had been substituted for some of the gold, then the crown would displace more water than the pure gold.

Write the steps for calculating molar mass.
Marizza181 [45]

Answer:

Explanation:

1) Find number of each of the type of atom that is present in the compound, using the chemical formula .

2) Then multiply number of atoms of each element that is present in the compound with the atomic weight of each of the element

3) Add everything together and add the units (grams/mole ) after the number

Let finds that of water

Chemical formula of water is (H20 )

hydogens atoms= 2

oxygen atom= 1

Atomic weight for Hydrogen= 1

Atomic weight for Oxygen= 16

Total number of atoms of Hydrogen from the formula (H2O)= 2

Total number of atoms of Oxygen from the formula (H2O)= 1

the molar mass=

Hydrogen: ( 2 x 1)= 2

Oxygen: ( 1 x 16)= 16

Add together= (16+2)

= 18

Then add the unit, we have(18 g/mol.)
