Explanation:
It is known that density is the amount of mass which is present in a liter of substance.
Mathematically, Density =
It is given that volume is 12 mL and density is 1.1 g/ml. Hence, the density will be calculated as follows.
Density =
1.1 g/ml =
mass = 13.2 g
Thus, we can conclude that mass of the given substance is 13.2 g.
Answer:
Protons and neutrons form the nucleus of the atom with electrons orbiting it.- C.
Answer is: <span>lumps os sugar dissolving in water.
Sugar has very good solubility in water and it dissolves readily, which is </span><span>example of a physical change.
</span>Gibbs free energy (G) determines if reaction will proceed
spontaneously, if ΔG is negative, reaction is spontaneous <span>(ΔG = ΔH - T·ΔS).
</span>In other examples, reactions are spontaneous in reverse way, for example spontaneous is forming sodium chlorine from sodium metal and chlorine gas, but not sodium chloride forming sodium metal and chlorine gas, because a lot of energy is needed for that reaction.
Answer:
9.00 g of H₂O
Explanation:
First calculate moles,
Moles = No. of Molecules / 6.022 × 10²³ Molecules/mol
Moles = 3.01 × 10²³ Molecules / 6.022 × 10²³ Molecules/mol
Moles = 0.50 moles
Now convert moles to mass,
Mass = Moles × M.Mass
Mass = 0.50 mol × 18.01 g/mol
Mass = 9.00 g of H₂O
