Calculate the density of an object with a mass of 3.8 g, that when placed in a 10.0 mL graduated cylinder with an initial volume

Arturiano [62]

Answer : The density of an object is 0.93 g/mL

Explanation : Given,

Mass of an object = 3.8 g

Initial volume = 4.5 mL

Final volume = 8.6 mL

First we have to calculate the volume of an object.

Volume of an object = Final volume - Initial volume

Volume of an object = 8.6 mL - 4.5 mL

Volume of an object = 4.1 mL

Now we have to calculate the density of an object.

Formula used:

$\text{Density}=\frac{\text{Mass of an object}}{\text{Volume of an object}}$

Now putting all the given values in this formula, we get:

$\text{Density}=\frac{3.8g}{4.1mL}$

$\text{Density}=0.93g/mL$

Therefore, the density of an object is 0.93 g/mL

A ground state hydrogen atom absorbs a photon of light having a wavelength of 92.30 nm. It then gives off a photon having a wave

dolphi86 [110]

energy provided=13.4 eV
energy released=0.7 eV
energy absorbed = 12.7eV
initial energy= -13.6eV [ground state]
final energy = -13.6+12.7 = -0.9 eV

This energy corresponds to n=4 in hydrogen atom

Air pressure decreases more rapidly with altitude within a column of ________ air than in a column of __________ air.

Anarel [89]

Air Pressure drops more rapidly with altitude in a column of cold air than in warm air.The answers to this question are cold air and warm air, respectively.
Cold air is known to be dense while warm air is known otherwise to be less thens which makes it move upwards. Cold air experiences more pressure as it moves upwards.

A balloon filled with air has a volume of 0.500 L at 25.0 ºC and an internal pressure of 1.20 atm. What will the volume of the b

Alex_Xolod [135]

Answer:

0.441 L

Explanation:

At constant pressure, Using Charle's law :-

$\frac {V_1}{T_1}=\frac {V_2}{T_2}$

Given ,

V₁ = 0.500 L

V₂ = ?

T₁ = 25.0 °C

T₂ = -10.0 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T₁ = (25 + 273.15) K = 298.15 K

T₂ = (-10 + 273.15) K = 263.15 K

Using above equation as:

$\frac{0.500}{298.15}=\frac{V_2}{263.15}$

$V_2=\frac{0.500\cdot \:263.15}{298.15}$

New volume = 0.441 L
