A bottle contains 2.5 moles of KOH dissolved in water, and the molarity of the solution is 0.16 M.
What volume of solution is in this bottle?
Answers
Answer:
V = 15.6 L
Explanation:
Hello there!
In this case, according to the definition of molarity in terms of the moles of solute divided by the volume of the solution, it is possible for us to write:
[tex]M=n/V[/tex]
Thus, given the moles and concentration of the solution, we can find the volume as shown below:
V=n/M
Therefore, we plug in the given data to obtain:
V = 2.5mol /(0.16mol/L)
V = 15.6 L

If you want to change the mass of your atom by 1 or more mass units, you can either? Add a proton and Add a neutron.
Explanation:
Option A and Option B is your answers.
To change the mass of your atom by more mass units ; you can add a proton or add a neutron ( A and B )
The nucleus of an atom is composed of a neutron and a proton while the outer shell of an atom comprises of the electrons.
The mass of an atom is dependent on the mass of the nucleus of the atom therefore to increase the mass of the atom by any number of mass units you can either add a proton or a neutron to the nucleus of the cell.
Hence we can conclude that to change the mass of your atom you can add a proton or add a neutron to the nucleus of the atom

how many moles of water is 5.02 x 10 18 molecules of water
Answers
Answer:
8.334×10^-6 moles
Explanation:
a mole is 6.023×10^23
5.02×10^18 ÷ 6.023×10^23=8.33×10^-6
so there are 8.33×10^-6 moles of water in 5.02x10^18 molecules of water
The number of moles of water in which 5.02 × 10¹⁸ molecules of water is present is 8.33 × 10⁻⁶.
What is moles?
Moles is a unit which is used to tells about the quantity of any substance, in one moles of any substance 6.023 × 10²³ number of atoms of that substances are present.
In 1 mole of water = 6.023 × 10²³ number of molecules of water is present
So, number of 5.02 × 10¹⁸ molecules of water present in how many moles will be calculated as:
Required moles = 5.02 × 10¹⁸ / 6.023 × 10²³ = 8.33 × 10⁻⁶
Hence, required moles is 8.33 × 10⁻⁶.

1. Cierta muestra fue diluida así: 1 mL MP se agrega 4mL de agua, luego se extrae 0,5 mL y se lleva a 5 mL y de esta última se obtiene 0,2 y se añade 1,3 de diluyente. Calcule la dilución total.
Answers
Answer:
1/375
Explanation:
Primero se debe calcular el factor de dilución para cada dilución seriada. Para ello, se divide el volumen de muestra entre el volumen final de la solución diluida.
1) 1 mL en 1 mL + 4 mL = 5 mL
D1 = 1 mL/5 mL = 1/5
2) 0,5 mL en 5 mL
D2 = 0,5 mL/5 mL = 1/10
3) 0,2 mL en 0,2 mL + 1,3 mL = 1,5 mL
D3 = 0,2 mL/1,5 mL = 2/15
La dilución total se calcula como el producto de las diluciones seriadas realizadas:
DT = D1 x D2 x D3 = 1/5 x 1/10 x 2/15 = 1/375
An 886 mL sample of Neon gas is at 752 torr and 299 K. What will be the new volume if, with the pressure and amount of gas held constant the temperature is increased to 371 K?
Answers
Answer:
[tex]V_2=1099.35mL[/tex]
Explanation:
Hello there!
In this case, according to the given information, it is possible to infer that as both the amount of the gas and the pressure remains the same, we can solve this problem via the Charles' law a directly proportional relationship between the volume and temperature:
[tex]\frac{V_2}{T_2} =\frac{V_1}{T_1}[/tex]
Thus, by solving for the final volume, V2, we obtain:
[tex]V_2 =\frac{V_1T_2}{T_1} \\\\V_2 =\frac{886mL*371K}{299K}\\\\V_2=1099.35mL[/tex]
