<h3>Answer:</h3>

48.95% (m/v)

<h3>Explanation:</h3>

From the question we are given;

  • Mass of solute, NaCl is 186 g
  • Volume of the solvent, water as 3.80 L or 380 mL

We are required to calculate the mass volume percent of solution;

How do we calculate the mass volume percent of a solution?

  • To calculate the mass volume percent, we use the formula,

Mass volume percent = (mass of solute in g/Volume of solvent in mL) 100

                                    = (186 g ÷ 380 mL)100

                                    = 48.95%

Therefore, the mass volume percent of a NaCl solution is 48.95% (m/v).

Answer:

It is just slightly less abundant than its alkali cousin, sodium. Potassium is less dense than water, so it can float on water. However, chemically, potassium reacts with water violently. It will give off hydrogen and eventually catch fire.

Lunna [17]

Answer:

The answer to your question is  1.83 x 10²⁵ particles

Explanation:

Data

particles of H₂O = ?

mass of H₂O = 546 g

Process

1.- Calculate the molar mass of Water

Molar mass = (2 x 1) + (1 x 16)

                   = 2 + 16

                   = 18 g

2.- Use proportions to find the number of particles. Use Avogadro's number.

                 18 g ---------------- 6.023 x 10²³ particles

                546 g ---------------   x

                  x = (546 x 6.023 x 10²³) / 18

3.- Simplification

                  x = 3.289 x 10²⁶ / 18

4.- Result

                  x = 1.83 x 10²⁵ particles

Natasha_Volkova [10]

Answer:

17.04%

Explanation:

Actual Value = 173.1

Measured Value = 143.6

Percent error is obtained using the equation;

Percent error = (Measured - Actual) / Actual ]* 100

Percent error = [ (143.6 - 173.1) / 173.1 ] * 100

The absolute value of (Measured - Actual) is taken,

Percent Error = [29.5 / 173.1 ] * 100

Percent Error = 0.1704 * 100 = 17.04%
