The density of whole milk 1.04 g per mL. What is the volume (in quarts) of 18.5 pounds of whole milk?

Chemistry
1 answer:
nadya68 [22]2 years ago

The volume : 8,526 quarts

<h3>Further explanation</h3>

Given

The density of whole milk = 1.04 g/ml

mass = 18.5 pounds

Required

The volume

Solution

Conversion of mass

1 pound = 453,592 g

18.5 pounds = 8391,45 g

Density formula:

\large{\boxed {\bold {\rho~=~ \frac {m} {V}}}}.

Input the value :

V = m : ρ

V = 8391,45 g : 1.04 g/ml

V = 8068.7 ml

1 ml = 0,00105669 quarts

8068.7 ml =8,526 quarts

Heating a carboxylic acid with a primary amine forms water along with what organic product? OA) A secondary amide OB) A primary
Bezzdna [24]

Answer:

A) secondary amide

Explanation:

When carboxylic acid reacts with a primary amine, a condensation reaction takes place with the elimination of a water molecule .

For example, ethanol reacts with methylamine which is a primary amine gives N-Methylacetamide and a water molecule as:

CH_3COOH+NH_2CH_3\rightarrow CH_3-CONH-CH_3+H_2O

The bond formed which is

  O

   ||

-- C  ---NH ---

is known as secondary amide group as only one hydrogen is attached to nitrogen atom in the amide bond.

Gaseous hydrogen and oxygen can be prepared in the laboratory from the decomposition of gaseous water. The equation for the reac
monitta

Answer:

  • 75.5 g O₂ (g) can be produced from 42.6 g of H₂O (g)

Explanation:

<u>1) Balanced chemical equation (given):</u>

  • 2H₂O(g) → 2H₂(g) + O₂(g)

<u>2) Mole ratios:</u>

  • 2 moles H₂O(g) : 2 moles H₂(g) : 2 moles O₂(g)

<u>3) Calculate the number of moles of reactant (H₂0):</u>

  • number of moles = mass in grams / molar mass

  • molar mass of water: 18.015 g/mol

  • mass in grams of water: 42.6 g

  • number of moles = 42.6 g / 18.05 g/mol = 2.36 moles H₂O

<u>4) Set a proportion using the mole ratio  O₂ to H₂O and the actual number of moles of H₂O:</u>

  • 2 moles O₂ / 2 moles H₂O = x / 2.36 moles H₂O

  • x = 2.36 moles O₂

<u>5) Convert 2.36 moles O₂ to grams:</u>

  • mass in grams = number of moles × molar mass

  • mass = 2.36 moles × 32.00 g/mol = 75.5 g O₂

A molecule can be made of which of the following? many elements a single element a single atom
o-na [289]

Answer: Option (a) is the correct answer.

Explanation:

When two or more atoms are chemically combined together then the product formed is known as a molecule.

These atoms can be bonded through either covalent or ionic bonds.

For example, a water molecule consists of two hydrogen atoms combined with an oxygen atom. Chemical formula of water is H_{2}O.

Thus, we can conclude that an element can be made of many elements.

What is the percent composition by mass of nitrogen in the compound N2H4 (gram-formula mass = 32 g/mol)?
Alex

Answer:

\large \boxed{93\, \% }

Explanation:

1. Calculate the molar mass of N₂H₄

2N = 2 × 14 = 28

4H = 2 ×  1  = <u>  4</u>

           Tot. = 32

2. Calculate the mass percent of N

\text{\% of element} = \dfrac{\text{mass of element}}{\text{mass of compound}} \times 100 \, \% = \dfrac{\text{28}}{\text{32}} \times 100 \, \% =\mathbf{88 \, \%}\\\\\text{The percentage of N in N$_{2}$H$_{4}$ is $\large \boxed{\mathbf{88\, \% }}$}}
