Given that the nucleophilic substitution reaction used 5.0 mL of t-pentyl alcohol and 12.0 mL of conc. hydrochloric acid to prod
Vladimir [108]

Answer:

4.90 g

Explanation:

Given that:

volume of t-pentyl alcohol = 5 mL

the standard density of t-pentyl alcohol = 0.805 g/mL

Recall that:

density = mass(in wt) /volume

mass = density × volume

mass = 0.805 g/mL × 5 mL

mass = 4.03 g

Volume of HCl used = 12 mL

The reaction for this equation is shown in the image attached below.

From the reaction,

88.15 g of t-pentyl alcohol reacts with concentrated HCl to yield 106.59 g pf t-pentyl chloride.

4.03 g of t-pentyl alcohol forms,

= \dfrac{106.59 \ g \times 4.03 \ g}{88.15 \ g} of t-pentyl chloride.

Therefore,

Theoretical yield of t-pentyl chloride = 4.90 g

Density is an intensive physical property that relates the mass of an object to its volume. Density, which is simply the mass of
xz_007 [3.2K]

Answer: 40731.8 grams of this gasoline would fill a 14.6gal tank

Explanation:

Density is defined as the mass contained per unit volume.

Density=\frac{mass}{Volume}

Given : Mass of gasoline = ?

Density of the gasoline = 0.737g/ml

Volume of the gasoline = 14.6gal = 55267.01 ml           (1gal=3785.41ml)

Putting in the values we get:

0.737g/ml=\frac{mass}{55267.01ml}

{\text {mass of gasoline}}=40731.8g

Thus 40731.8 grams of this gasoline would fill a 14.6gal tank

Where does most of the mass of an atom come from? What parts of the atom make it up?
motikmotik

Answer:

nucleus

Explanation:

The majority of an atoms' mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom's constituent particles, with a mass of 9.11 x 10-31 kg and a size too small to be measured by current techniques.

If a sample of CO gas at 1.977 atm has a volume of 517.4 mL and the pressure is changed to
Mekhanik [1.2K]

Answer:

The answer to your question is V2 = 333.9 ml

Explanation:

Data

Pressure 1 = P1 = 1.977 atm

Volume 1 = V1 = 517.4 ml

Pressure 2 = P2 = 3.063 atm

Volume 2 = V2 = ?

Process

To solve this problem use Boyle's law

              P1V1 = P2V2

-Solve for V2

              V2 = P1V1/P2

-Substitution

              V2 = (1.977 x 517.4) / 3.063

-Simplification

              V2 = 1022.9 / 3.063

-Result

              V2 = 333.9 ml
