Chelsea adds a 65% acid solution to 25 milliliters of a solution that is 30% acid. How much of the 65%
acid solution should be added to create a solution that is 40% acid?

Answers

Answer:

10 ml

Explanation:

The concentration of the acid solution Chelsea adds to the 25 milliliters of 30% acid solution = 65%

The concentration of the acid solution Chelsea requires = 40%

The volume, X, of the 65% acid solution required is given as follows;

65% × X + 30% × 25 = 40% × (25 + X)

As fractions, we have;

0.65 × X + 0.3 × 25 = 0.4 × (25 + X)

0.65·X + 7.5 = 10 + 0.4·X

0.65·X  - 0.4·X = 10 - 7.5

0.25·X = 2.5

X = 2.5/0.25 = 10

X = 10 ml

The volume of the 65% acid that should be added to create a solution that is 40% acid = 10 ml.

i need help ASAP ! Please

Answers

Answer:

Your friend gave the better response

Explanation:

Formula for density:

Density = mass/volume

p = m/v

Let's substitute the given values into the equation:

p = m/v

p = 23.2/8.593

Solve:

p = 23.2/8.593

p = 2.69987198883

2.69987198883 grams per volume

Notice that 2.69987198883 is the exact answer. Your answer is 2.67, which is inaccurate, even if rounded. If you were to round the exact answer to the nearest hundredth, it would be 2.70 which is not 2.67.

Therefore, your friend gave the better response because it is the correct answer.

density equals mass over volume

23.2/8.593 = 2.69 g/mL

A chemist must prepare of aqueous copper(II) sulfate working solution. He'll do this by pouring out some aqueous copper(II) sulfate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in of the copper(II) sulfate stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits.

Answers

Answer:

380 mL

Explanation:

A chemist must prepare 925 mL of 325 mM aqueous copper(II) sulfate working solution. He'll do this by pouring out some 0.792 M aqueous copper(II) sulfate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the copper(II) sulfate stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits.

Step 1: Given data

Initial concentration (C₁): 0.792 MInitial volume (V₁): ?Final concentration (C₂): 325 mMFinal volume (V₂): 925 mL

Step 2: Convert "C₂" to M

We will use the conversion factor 1 M = 1000 mM.

325 mM × (1 M/1000 mM) = 0.325 M

Step 3: Calculate the inital volume

We will use the dilution rule.

C₁ × V₁ = C₂ × V₂

V₁ = C₂ × V₂/C₁

V₁ = 0.325 M × 925 mL/0.792 M

V₁ = 380 mL

A boy found a solid metal box in his backyard. The box had been buried for so long, it was difficult to determine from what the box was made. The boy measured the box and found its volume (v) to be 17.63 cubic centimeters (cm3) and its mass (m) to be 158 grams (g). The boy knows the formula for density (D) is D = m/v. This table shows the density of several metals. DENSITY OF METALS *

A. copper
B. gold
C. silver
D. tin​

Answers

Answer:

Box is made up of copper, because density is 8.96  g/cm³.

Explanation:

Given data:

Volume of box = 17.63 cm³

Mass of box = 158 g

Which metal box is this = ?

Solution:

First we will calculate the density of box then we will compare it with the density value of given metals.

d = m/v

d = 158 g/ 17.63 cm³

d = 8.96  g/cm³

The calculated density is similar to the given density value of copper thus box is made up of copper.
