If 4.89 g of ZnCl2 is dissolved in enough water to give a total volume of 500 mL, what is the molarity of the solution

Chemistry
1 answer:
Molodets [167]2 years ago
5 0

Answer:

Molarity = 0.08 M

Explanation:

Given data:

Mass of ZnCl₂ = 4.89 g

Volume of water = 500 mL (500 mL× 1L/1000 mL= 0.5 L)

Molarity of solution = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Number of mole ZnCl₂:

Number of moles = mass/molar mass

Number of moles = 4.89 g/ 136.3 g/mol

Number of moles = 0.04 mol

Molarity:

M = 0.04 mol / 0.5 L

M = 0.08 M

Why was meteorology such a late developer compared to other branches of science?
Sedaia [141]

Answer:

Because of the difficulties of measuring the atmosphere's properties above the earth's reachable surface

Explanation:

Hello,

In this case, meteorology is the branch of science studying the atmosphere in its weather processes and forecasting and it had a late development because of the difficulties of measuring the atmosphere's properties above the earth's reachable surface. We cannot forget that even nowadays, it is very difficult to predict upcoming weathers with the 100 % assurance and with many days in advance.

Best regards.

2. How much force will this car experience if it collides with a wall and the collision lasts for
Pepsi [2]

The momentum of the body is 12 m/s.

<h3>What is momentum?</h3>

Momentum is the product of the mass of a body and velocity. According to Newton's second law, the rate  of change of momentum is equal to the impressed force.

The details required to answer the first two questions are missing hence we can't answer those questions. For the last question;

p = mv

m = mass

v = velocity

p = momentum

v = p/m

v =  72,000 kgm/s/6,000 kg

v = 12 m/s

¿Cuál será la masa molar del agua?, si el hidrógeno tiene una masa atómica H=1.0 uma y el Oxigeno de 16 uma. * 1 punto
nataly862011 [7]

Answer:

18

Explanation:

Sabemos que la fórmula química del agua es H2O.

Usando la información que; H = 1, O = 16, podemos calcular la masa molar del agua de la siguiente manera

[2 (1) + 16] = 18

Por tanto, la masa molar del agua es 18
