Ethanol has a density of 0.789 g/cm3. What is the mass of 423 cm3 of ethanol? M = (D)(V)

Ivahew [28]

Answer:

<h2>The answer is 334 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of ethanol = 423 cm³

density = 0.789 g/cm³

So we have

mass = 0.789 × 423 = 333.747

We have the final answer as

Classify the following substances as a Bronsted-Lowry acid, Bronsted-Lowry base, Lewis acid, and/or Lewis base.

Margarita [4]

Answer :

HCl : Bronsted-Lowry acid

$BF_3\text{ and }^{+}CCl_3$ : Lewis-acid

$^-H, CH_2O,^-OCH_3\text{ and }NH_3$ : Bronsted-Lowry base

$^-H, CH_2O,^-OCH_3,CH_3Cl\text{ and }NH_3$ : Lewis-base

Explanation :

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

HCl :

It is a Bronsted-Lowry acid that donates protons.

$BF_3\text{ and }^{+}CCl_3$ :

It is a Lewis-acid that accepts electron pairs.

$^-H, CH_2O,^-OCH_3\text{ and }NH_3$ :

It is a Bronsted-Lowry base that accepts protons.

$^-H, CH_2O,^-OCH_3,CH_3Cl\text{ and }NH_3$ :

It is a Lewis-base that donates electron pairs.
