What volume of a 6.0m hcl solution is required to make 250.0 milliters of 1.5 m hcl
Georgia [21]

Answer : The volume for 6.0m HCl solution required = 62.5 ml

Solution : Given,

Initial concentration of HCl solution = 6.0m

Final concentration of HCl solution = 1.5m

Final volume of HCl solution = 250 ml

Initial volume of HCl solution = ?

Formula used for dilution is,

M_1V_1=M_2V_2

where,

M_1 = initial concentration

M_2 = final concentration

V_1 = initial volume

V_2 = final volume

Now put all the given values in above formula, we get the initial volume of HCl solution.

6.0m\times V_1=1.5m\times 250ml

V_1 = 62.5 ml

Therefore, the volume for 6.0m HCl solution required = 62.5 ml

What volume in liters, l, of solution should sven prepare if he wants to make a 5.00 m solution using 210.0 grams, g, of sodium
weeeeeb [17]

To make a 5.00 M solution using 210.0 grams, g, of sodium chloride, NaCl, we will use the formula of volume of solution in liters is equal to mole of solute per molarity of solution, which is 0.718 L.

Molarity (M) refers to the amount of a substance in a specific volume of solution. It is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution.

Molarity  is given by the quotient,

Molarity = moles of solute/volume of solution in liters.

Now in order to get the molarity of the solution, we have to divide the moles of solute over the liters of solution. Since we are given the mass of the solute, we must first convert the mass of NaCl into moles with the help of the molar mass of NaCl as a conversion factor.

210 NaCl x ( 1 mol NaCl/ 58.44g NaCl) = 3.59 mol NaCl.

We already have the molarity of the solution that is 5.00 M. So the solution to find out the volume will be,

Volume of solution in liters = mole of solute/ molarity of solution,

That is 3.59 mol NaCl / 5M = 0.718 L

A neutralization reaction was carried out in a calorimeter. The change in temperature (∆T) of the solution was 10.9 °C and the m
BabaBlast [244]

Answer:

The correct answer is 4,556.2 J

Explanation:

The amount of heat is calculated with the following equation:

Heat= m x Cs x ΔT

Given:

m= 100.0 g (mass)

Cs= 4.18 J/g.ºC (specific heat)

ΔT= 10.9ºC (change in temperature)

We introduce the data in the equation and calculate the heat:

Heat = 100.0 g x 4.18 J/ºC.g x 10.9ºC = 4,556.2 J

Therefore, the amount of heat absorbed by the water (gained by the solution) is 4,556.2 J
