Answer:
0.250L of solution. 0.250 moles of solute.
Explanation:
As you can see in the image, there is a beaker with an amount of solution. 1/2L are 500mL and each line of the beaker represents 100mL. That means the volume of the solution is approximately 250mL = 0.250L
Molarity is an unit of concentration defined as the moles of solute per liter of solution. A solution that is 1.000M contains 1.000 moles of solute per liter of solution.
As the volume of the solution is 0.250L, the moles are:
0.250L * (1.000mol/L) = 0.250 moles of solute
Answer:
dCDP
Explanation:
The nucleotide has hydrogen at it second carbon which means that it has deoxy pentose sugar which is written in small d as prefix.
The nitrogenous base is cytosine and it contains 2 phosphate groups which are attached to the 5 carbon of the pentose sugar means it is cytosine diphosphate.
<u>So, the abbrevation of the molecule is : dCDP</u>
Answer:
Because carbon has one more proton than boron. Carbon has six and Boron has five.
Explanation:
Because it has more subatomic particles. It has one more proton, one more neutron (usually), and one more electron than boron.
Answer : The concentration of the resulting solution is, 0.0074 M
Explanation :
Formula used :
where,
are the initial molarity and volume of stock solution.
are the final molarity and volume of diluted solution.
We are given:
Putting values in above equation, we get:
Hence, the concentration of the resulting solution is, 0.0074 M
