Which element has the greatest density at stp? calcium, chlorine, carbon or copper?
ludmilkaskok [199]
Density = mass/volume

Since at STP, one mole of any gas occupies 22.4 liters, therefore, the volume is equal.
So, we will arrange based on mass.

From the periodic table:
mass of carbon = 12 grams
mass of calcium = 40 grams
mass of chlorine = 35.5 grams
mass of copper = 63.5 grams

Based on this:
copper has the highest density.

Substrate: N-benzoyl-L-tyrosine ethyl ester (BTEE) 0.001M in 50% aqueous
andreev551 [17]

0.1 mL of the stock solution of the enzyme is taken and made up to 5.0 mL with 0.001M HCl in order to prepare a 50-fold diluted enzyme.

<h3>What is dilution?</h3>

Dilution is a process of making a solution of lower concentration from a solution of higher concentration by the addition of solvent to a given volume of the solution of higher concentration.

Dilution of solutions is done using the dilution formula in order to determine the given volume of diluent or stock solution required. The dilution formula is given below:

  • C1V1 = C2V2

where:

  • C1 = Initial concentration of enzyme
  • C2 = Final concentration of enzyme
  • V1 = Initial volume
  • V2 = Final volume

For the enzyme dilution;

C1 = 1 mg/mL

C2 = 1/50 mg/ml = 0.02 mg/ml

V= ?

V2 = 5 ml

V1 = C2V2/C1

V1 =  0.02 * 5/1 = 0.1 mL

Therefore, 0.1 mL of the stock solution of the enzyme is taken and made up to 5.0 mL with 0.001M HCl in order to prepare a 50-fold diluted enzyme.

A pumpkin has a volume of 10 cm and a mass of 8 g. what is the density of the pumpkin​
cricket20 [7]

Answer: 0.8g/cm^3

Explanation:

In seeing your problem, I see an issue with your units for centimeter. The volume is in the third dimension, so we use cm^3 every single time for the volume. That way, we can arrive to the correct density (in g/cm^3)

Density = mass/volume and so

Density = 8g/10cm^3

= 0.8g/cm^3
