Answer:

71.8 g

Explanation:

With the first sentence we can calculate the density of the sample of glycerol:

Density=\frac{mass}{volume}

Density=\frac{25.2g}{57mL}\\Density=1.26g/mL

<u>Using the density of the sample we calculate the mass of a given volume:</u>

Volume*Density=Mass

57 mL * 1.26 g/mL = 71.8 g

A 57 mL sample of glycerol weighs 71.8 g.

Answer:

Density = 25.2 g/20.0 ml = 1.26 g/ml

57 ml x 1.26 g/ml = 71.8 g

Calculate the pH during the titration of 30.00 mL of 0.1000 M HCOOH(aq) with 0.1000 M NaOH(aq) after 29.3 mL of the base have be
pashok25 [27]

Answer:

3.336.

Explanation:

<em>Herein, the no. of millimoles of the acid (HCOOH) is more than that of the base (NaOH).</em>

<em />

So, <em>concentration of excess acid = [(NV)acid - (NV)base]/V total</em> = [(30.0 mL)(0.1 M) - (29.3 mL)(0.1 M)]/(59.3 mL) = <em>1.18 x 10⁻³ M.</em>

<em></em>

<em> For weak acids; [H⁺] = √Ka.C</em> = √(1.8 x 10⁻⁴)(1.18 x 10⁻³ M) = <em>4.61 x 10⁻⁴ M.</em>

∵ pH = - log[H⁺].

<em>∴ pH = - log(4.61 x 10⁻⁴) = 3.336.</em>
