Answer:
3.40g/mL
Explanation:
Density is a measure of mass over volume, so to get the density all we have to do is divide the mass by the volume.
21.35g ÷ 6.28 mL = 3.40g/mL
Answer:
1.915e23 Atoms
Explanation:
There are 6.02214076e23 is the mass of a mol in amu. Since the amu of lead is 207.2, and there is 65.89 grams of it, you can find that it creates approximately 1.914 atoms.
Answer:
Explanation:
The expression for centrifugal force is shown below as:-
Where, m is the mass of the object = ?
v is the velocity of the object = 7.60 m/s
r is the radius
F is the force = 222 N
Diamter = 11.6 m
Radius = d/2 = 11.6 m/2 = 5.8 m
Applying the values in the above expression as:-
130.03175 g. Mol to mass is multiplication. So multiply 5.35 by 24.305 and you will get the answer
Answer:
it increases
Explanation:
when particles increase pressure increases
