Answer:
0.12 mole.
Explanation:
From the question given above, the following data were obtained:
Molarity of NaCl solution = 0.1 M
Volume of NaCl solution = 1.2 L
Mole of NaCl =.?
Molarity of a solution is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
Molarity = mole /Volume
Thus, we can obtain the mole of NaCl in the solution by using the above formula as follow:
Molarity of NaCl solution = 0.1 M
Volume of NaCl solution = 1.2 L
Mole of NaCl =.?
Molarity = mole /Volume
0.1 = mole of NaCl /1.2
Cross multiply
Mole of NaCl = 0.1 × 1.2
Mole of NaCl = 0.12 mole
Therefore, 0.12 mole of NaCl is present in the solution.
Ethyl benzoate, (C9H10O2)<span>, is an </span>ester<span> formed by the condensation of </span>benzoic acid (which is a carboxylic acid)<span> and </span><span>ethanol (alcohol)
When you see a molecule named like *****yl ****ate it's probably an ester. Its name regroup the name of the carboxylic acid (which ends by "ate") and an alkyl (derivated from the alcohol)</span>

Answer:
No, there are some organisms that only have one cell, although there are organ systems that are made up of many cells. Not all organisms have organ systems.
Explanation:
For example, the Trichoplax. It is an animal with no organs that is tiny and multicellular, and only feeds on microalgae. A Trichoplax are flat organisms about a millimetre in diameter with no internal structures and typically have two cellular layers. These organisms live in the oceans and seas all around the world but are not necessarily found in their natural habitat, more so in captivity such as a marine aquarium. Trichoplax are found to live in symbiosis with such things as bacteria and others in the oceans and seas.
Add proton + neutrons = Mass 37
Proton is same as your atomic mass= 17
If you go on the periodic table look up 17 and it will give u the letter.
