Answer is: mass of acetone is 22.51 grams.:
V(acetone - C₃H₆O) = 28.66 mL; volume.
d(acetone) = 0.7857 g/mL; density.
m(acetone) = V(acetone) · d(acetone).
m(acetone) = 28.66 mL · 0.7857 g/mL.
m(acetone) = 22.51 g; mass.
Acetone<span> or </span>propanone is the <span>colorless, volatile, flammable </span>organic compound (ketone).
Answer:
Density is 7.15 g /mL.
Mass is 445.2 g.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Mass of first zinc sample = 210.10 g
Mass of second zinc sample = 235.10 g
Combined volume = 62.3 mL
Density of combined sample ?
Mass of combined sample = ?
Solution:
Mass of combined sample = 210.10 g + 235.10 g = 445.2 g
density = mass / volume
density = 445.2 g / 62.3 mL
density = 7.15 g /mL
Answer:
Cells need to maintain homeostasis in order for our body to be healthy and fully functional. If the internal conditions of our cells are not stable, then the normal cell functions would be disrupted.
Explanation:
<u>Answer:</u> The products of the given chemical equation are
<u>Explanation:</u>
Protonation equation is defined as the equation in which protons get added in the substance.
The chemical equation for the protonation of carbonate ion in the presence of water follows:
By Stoichiometry of the reaction:
1 mole of carbonate ion reacts with 1 mole of water to produce 1 mole of hydrogen carbonate ion and 1 mole of hydroxide ion
Hence, the products of the given chemical equation are
Answer: Small molecular structure
Explanation:
> Bromine and Hydrogen are both non-metals, so they hence cannot form ionic compounds and metals. As such, Ionic Lattice and Metallic structure is wrong.
> gaseous Hydrogen Bromide HBr is produced. Giant covalent substances, such as diamond, have very high melting and boiling points. As such, HBr is a small molecular structure, or a simple covalent substance.
