The density of benzene at 15 ∘C∘C is 0.8787 g/mL. Calculate the mass of 0.1700 LL of benzene at this temperature. Express your a
SVETLANKA909090 [29]

Answer:

Mass of benzene is: 149.3 g

Explanation:

Let's use density to calculate mass.

Density = Mass / Volume

Mass = Density . volume

Be careful, because density is in g/mL and the volume is in L. So let's convert the L to mL: 0.170 L . 1000 mL / 1L = 170 mL

0.8787 g/mL . 170 mL = Mass of benzene

Mass of benzene is: 149.3 g

storchak [24]
  • <em>Answer:</em>

<em>≈ 4.10 g/cm³</em>

  • <em>Explanation:</em>

<em>Hi there ! </em>

<em><u /></em>

<em><u>Density formula</u></em>

<em>d = m/V</em>

<em>d = 6.13g/1.5cm³</em>

<em>d = 4.08(6) g/cm³ ≈ 4.10 g/cm³</em>

Write a 125 word summary of what you have learned in "Introducing the Microscope". Be sure to include steps on how to focus, how
Rina8888 [55]

Answer:

Introduction to Basic Microscopy. Microscopes are specialized optical instruments designed to produce magnified visual or photographic (including digital) images of objects or specimens that are too small to be seen with the naked eye.

Microscope are the important tools which are used by scientist. For example, in material science, medicine, mineralogy and microbiology.

Light microscope is able to send light. Light is being focused in a tight breath whereby that light passes through a sample which later it is able to create an image. This image passes to different lenses which magnifies it until it reaches the camera.

There are different types of microscope for example, Compound light microscope, Simple light microscope, and monocular microscope.

In simple light microscope only one lens which which is being used to magnify an object and it is not able to reach to a higher magnification.

In compound light microscope it uses two lenses to produce image. For example eyepiece lens and objective lens.

The specific heat of gold is 0.031 calories/gram°C. If 10.0 grams of gold were heated and the temperature of the sample
IgorLugansk [536]

Answer:

6.2 calories

Explanation:

Data Given:

change in temperature = 20 °C

specific heat of gold = 0.031 calories/gram °C

mass of gold = 10.0 grams

Amount of Heat = ?

Solution:

Formula used

             Q = Cs.m.ΔT

Where:

Q = amount of heat

Cs = specific heat of gold = 0.031 calories/gram °C

m = mass

ΔT = Change in temperature

Put values in above equation

                Q = 0.031 calories/gram °C x 10.0 g x 20 °C

                Q = 6.2 calories

So option A is correct = 6.2 calories
