If a person takes 30 ml of vinegar a day and the molarity of the vinegar is 0. 84 m then how many grams of acetic acid (hc2h3o2
babunello [35]

The mass of the acetic acid is 1.512 g.

<h3 /><h3>What is Molarity?</h3>

molarity is the concentration of a substance in mol per dm³

From the question,

The number of moles contained in the 30 mL vinegar is

  • n = (0.84×30)/1000
  • n = 0.0252 mol.

the molar mass of vinegar is calculated below.

  • m.m of (HC₂H₃O₂) = [1+(12×2)+(1×3)+(16×2)]
  • m.m = (1+24+3+32]
  • m.m = 60 g/mol.

To calculate the mass of acetic acid, we use the formula below.

  • R.m = n×m.m............. Equation 1

Where

  • R.m = mass of acetic acid.

Substitute these values into equation 1

  • R.m = (0.0252×60)
  • R.m = 1.512 g.

Hence, The mass of the acetic acid is 1.512 g.

Point (20, 5) is on the graph of inverse variation. Which of the following ordered pair is on the graph?.
Bess [88]

The point (10, 10) is on the graph.

<h3>Procedure - Inverse variation</h3><h3 /><h3>Inverse variation model</h3><h3 />

An <em>inverse</em> variation is represented by the following formula:

y = \frac{k}{x} (1)

Where:

  • x - Independent variable.
  • y - Dependent variable.
  • k - Proportionality constant.

We can eliminate the proportionality constant by creating the following relationship:

x_{1}\cdot y_{1} = x_{2}\cdot y_{2} (2)

<h3>Determination of another point</h3>

If we know that x_{1} = 20, y_{1} = 5 and x_{2} = 10, then the remaining variable is:

y_{2} = \left(\frac{x_{1}}{x_{2}} \right)\cdot y_{1}

y_{2} = \left(\frac{20}{10} \right)\cdot (5)

y_{2} = 10

The point (10, 10) is on the graph. (Correct choice: C) \blacksquare

The statement is incomplete. Complete form is described below:

<em>Point </em>(20, 5)<em> is on the graph of an inverse variation. Which of the following ordered pair is on the graph? </em><em>A.</em><em> </em>(4,1)<em>, </em><em>B.</em><em> </em>(2, 25)<em>, </em><em>C.</em><em> </em>(10, 10)<em>, </em><em>D.</em><em> </em>(16, 4)<em>.</em>
