Volume = 287 - 206 
v= 81 mL 

Mass= density x volume 
m = 11.3 x 81 
m = 915.3 g

Answer:

915 g

Explanation:

The volume of lead (V) is equal to the difference between the final level of water and the initial level of water.

V = 287 mL - 206 mL = 81.0 mL

The density of lead (ρ) is 11.3 g/mL. We can find the mass of lead (m), in grams, using the following expression.

ρ = m/V

m = ρ × V

m = 11.3 g/mL × 81.0 mL

m = 915 g

How would Bohr model show the protons in a carbon atom
MariettaO [177]

Answer:

The Bohr model show the protons in a carbon atom using the model;  "Electrons move in fixed orbits around a nucleus of protons and neutrons."

According to Bohr's model of the atoms, the Rutherford model is basically correct. This implies that Bohr model accepts the idea of a nucleus containing nucleons(protons and neutrons).

In addition, the model also postulates that electrons are found in fixed orbits. These fixed orbits are called energy levels or shells.

A graphic description of this is shown in the image attached to this answer.

How to separate crystals from solution​
tatiyna

Answer:

If a saturated hot solution is allowed to cool, the solute is no longer soluble in the solvent and forms crystals of pure compound. Impurities are excluded from the growing crystals and the pure solid crystals can be separated from the dissolved impurities by filtration.
