Answer:

Repetition

Explanation:

In the world of science, experiments are regularly conducted to test out hypotheses. These experiments are however, not conducted by scientist once to derive a result. They are rather conducted multiple times (repeated) to ascertain the accuracy i.e not as a result of random occurrence. The experiments that undergo multiple trials are said to undergo REPETITION.

This is the case of the scientist in this question, who is conducting an experiment to test what temperature causes the fastest growth rate in sunflower plants. He conducted the experiment multiple times, making it an example of REPETITION.

N.B: Replication is when the experiment is re-conducted by another scientist to see if same result is derived.

Phoenix [80]

Answer:

0.00676 M

Explanation:

A chemist prepares a solution of calcium bromide by weighing out 0.607g of calcium bromide into a 450ml volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's calcium bromide solution. Be sure your answer has the correct number of significant digits.

Step 1: Given data

Mass of calcium bromide (solute): 0.607 g

Volume of solution: 450 mL

Step 2: Calculate the moles corresponding to 0.607 g of calcium bromide

The molar mass of CaBr₂ is 199.89 g/mol.

0.607 g × 1 mol/199.89 g = 0.00304 mol

Step 3: Convert the volume of solution to liters

We will use the conversion factor 1 L = 1000 mL.

450 mL × 1 L/1000 mL = 0.450 L

Step 4: Calculate the molar concentration of calcium bromide

The molarity of the solution is:

M = moles of solute / liters of solution

M = 0.00304 mol / 0.450 L

M = 0.00676 M

In which way are a prokaryotic cell and a eukaryotic cell alike?  
inessss [21]
Prokaryotic cells do not contain membrane-closed organelles, (??) and they are not the same size at all. (prokaryotic are way smaller) Just to help narrow down, if I'm right! (: Sorry, I know that's not completely helpful.

Convert 9.32x 10 23ª atoms of au to moles of au
7nadin3 [17]

Answer:

\huge\boxed{\sf no.\ of\ moles = 1.55\ moles }

Explanation:

<u>Given:</u>

Number of atoms = 9.32 \times 10^{23} atoms

Avogadro's Number = 6.023 \times 10^{23} atom / mol

<u>Required:</u>

Moles = ?

<u>Formula:</u>

\displaystyle No.\ of\ moles = \frac{no. \ of \ atoms }{avogadro's \ no.}

<u>Solution:</u>

\displaystyle no. \ of \ moles = \frac{9.32\times 10^{23}}{6.023 \times 10^{23}}

no. of moles = 1.55 moles

\rule[225]{225}{2}

Hope this helped!
