Answer : The density of the object will be, 0.111g/cm^3

Explanation :

Density : It is defined as the mass contained per unit volume.

Formula used for density :

Density=\frac{Mass}{Volume}

Given :

Mass of an object = 5.0 grams

Volume = 45.0cm^3

Now put all the given values in the above formula, we get the density of an object.

Density=\frac{5.0g}{45.0cm^3}=0.111g/cm^3

Therefore, the density of the object will be, 0.111g/cm^3

1. A light bulb is filled with 3.54 g of argon at 25 C and 725 mmHg. What is
Ugo [173]

Answer: The volume of given gas is 2.27 L.

Explanation:

Given: Mass = 3.54 g

Temperature = 25^{o}C = (25 + 273) K = 298 K

Pressure = 725 mm Hg (1 mm Hg = 0.00131579) = 0.95 atm

As moles is the mass of substance divided by its molar mass.

So, moles of argon (molar mass = 40 g/mol) is as follows.

Moles = \frac{mass}{molar mass}\\= \frac{3.54 g}{40 g/mol}\\= 0.0885 mol

Formula used to calculate the volume of given gas is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

PV = nRT\\0.95 atm \times V = 0.0885 mol \times 0.0821 L atm/mol K \times 298 K\\V = 2.27 L

Thus, we can conclude that the volume of given gas is 2.27 L.

When attempting a Grignard reaction, you add the correct molar amount of acetone but what you didn’t know was that your lab part
DerKrebs [107]

Answer:

The products formed are

2-methyl-3-isopropylnonan-3-ol and 2-methyloctan-2-ol

The products should be in equal ratio since an equipmolar amount of acetone and 2,4-dimethylpentan-3-one was initially present as reactants

Explanation:

Ketones reacts with gridnard reagents to form tertiary alcohol, and since acetone and 2,4-dimethylpentan-3-one are both ketones, gridnard reagent reduced both to tertiary alcohols:2-methyl-3-isopropylnonan-3-ol and 2-methyloctan-2-ol
