M = n/V
M = 1.51
V = 0.730
1.51 = n/0.730
To solve this, multiply both sides by the V.
1.1023 = n
n = 1.1023 mol
Answer:
Explanation:
Be careful. The tricky part of the problem is that there are 4 places of sig digs.
m = 6.557 grams
V = 11.16 - 10.50 = 0.66
density = mass/ volume
density = 6.557/0.66 = 9.935 g/mL
Answer:
This question needs more detail. it dosnt really make sense.
Explanation:
Answer:
Physical properties are defined as the properties which can be observed without changing its chemical composition. For example: color, volume, and molecular weight. Chemical properties are defined as the properties which can be observed only after changing chemical identity of the substance.

Answer:
A & B
Explanation:
The answer for the first one is A because the proton is found in the nucleus with the neutron
The answer for the second was is B because the Neutrons, protons and electrons are all subatomic particles, as they are the main particles that make up an atom.
Proton = Positive Charge (+)
Neutron = Neutral charge (=)
Electron = Negative Charge (-)
