Using a mass of 1. 8 g and the volume displaced by the sample, calculate the sample's density. Question 17 options: 0. 17 g/mL 0
LUCKY_DIMON [66]

The sample's density with respect to the volume it displaces is equal to: C. 0. 60 g/mL

<u>Given the following data:</u>

  • Mass = 1.8 grams
  • Initial volume = 20 mL
  • Final volume = 23 mL

To calculate the sample's density:

First of all, we would determine the volume displaced by the sample;

Volume \;displaced = 23-20

Volume displaced = 3 mL

Density can be defined as mass all over the volume of an object. Thus, density is mass per unit volume of an object.

Mathematically, the density of a substance is given by the formula;

Density = \frac{Mass}{Volume}

Substituting the given parameters into the formula, we have;

Density = \frac{1.8}{3}

Density = 0.60 g/mL

Prove that the rate of heat production in each of the two resistors connected in parallel is inversely proportional to the resis
Viktor [21]
I believe that the answer to the question provided above is that with increase in resistance provided with constant current, Power dissipated will be lessen since power loss is high. Low power dissipation has low heat production.
Hope my answer would be a great help for you.

Is molded bread a physical or chemical change?
V125BC [204]
<span>A molded bread is a good example of a chemical change. A chemical change is a kind of change in which a new substance is formed. In a chemical change, the original substance which started the reaction can not be recovered.The molded bread formed in this given instance is a new substance which is different from the original bread, so also, the original bread can no longer be retrieved from the molded bread.</span>
