Answer:
Density = 0.0035 g/cm³
Explanation:
The density equation looks like this:
Density (g/cm³) = mass (g) / volume (cm³)
You have been given both the mass and volume. However, the given volume is not in the correct units. To convert cm to cm³, you should simply raise the given volume to the power of 3.
24 cm = (24 cm)³ = 24³cm³ = 13,834 cm³
Now, you can plug you mass and volume into the equation and solve for density. The final answer should have 2 sig figs to reflect the given values.
Density = mass / volume
Density = 48 g / 13,824 cm³
Density = 0.00347 g/cm³
Density = 0.0035 g/cm³
Answer:
i'm not sure but i think
Explanation:

density The amount of matter in a given volume of space.
formula for density mass divided by volume
physical property A property of matter that can be observed and measured, without changing its identity.
I hope it helps
Answer:
The pH of a solution with a (H+] = 0.80 M is 
Explanation:
As we know
pH = -[log H+]
Substituting the value of H+ ion concentration in the above equation, we get -
pH = -log [0.80]
pH ![= -[-0.096] = 0.096 = 9.6 e^{-2}](https://tex.z-dn.net/?f=%3D%20-%5B-0.096%5D%20%3D%200.096%20%20%3D%209.6%20e%5E%7B-2%7D)
1 mole of particles = 6.02*10²³
8.59 *10²³atoms*(1 mol/6.02*10²³ atoms) = (8.59/6.02) mol
M(Cl)=35.5 g/mol
(8.59/6.02) mol*35.5 g/mol=50.7 g
