To determine the number of molecules in 10.0 g of C8H8O3, we need to calculate the number of moles first. The molar mass of C8H8O3 is 152.15 g/mol. By dividing 10.0 g by the molar mass, we find that there are approximately 0.0658 moles of C8H8O3. To convert moles to molecules, we multiply the number of moles by Avogadro's number, 6.022 x 10^23, giving us about 3.96 x 10^22 molecules.

How many substances are present in a water and salt mixture?
depends on what salt it is and the purity of the water. if the water is 100% pure , then it contains only hydrogen and oxygen as molecules and if it is common salt then it contains sodium and chlorine as molecules
How many molecules of H2O make up one cup of water?
For a 100 mL cup: approx. 35,45.1023 molecules.
Is pure water a conductor or a non-conductor?
100% Pure water is not a conductor (insulator) However, please remember, minerals in not 100% pure water are conductors and there are about 10 million minerals in 1 cup of water. It can electrify you. So becareful.
The number of molecules in a teaspoon of starch is?
about 100
Why when you mix exactly one liter each of pure ethanol and pure water do you end up with less than exactly two liters of liquid?
due to the inerrant structure of alcohol, the water molecules tend to fit into the spaces in the alcohol molecules,thus resulting in some extra space having been left by the absorption of the water molecules by the alcohol molecules this results in a volumetric deficit in the total sum of both liquids.The proof of the alcohol would then be exactly 1/2 of the original value assuming that at 100% pure alcohol and 100 % pure water ,after mixing the two ,the alcohol is now at 50% of its original strength or 100 proof after starting out as 200 proof ,therefore proof is 2 times the amount of alcohol (200 proof alcohol diluted with an equal amount of water yields slightly less than 2 liters of 100 proof or 50 % alcohol. here ends chemistry 101. surprising that all the big time answerer s could not come up with an answer,so much for credibility

How many milliliters do you get out of 100 milligrams?
Only if you have pure water in mind, then: 0.1 milliliters of pure water weigh 0.1 grams or 100 milligrams.
100 kilograms of pure water would have a volume of how many liters?
100. Pure water has a density of 1000Kg/M3, which is also 1kg/liter So 100Kgs = 100 l

How many grams is equal to 100 milliliters?
Only if you have pure water in mind, then: 100 milliliters of pure water weigh 100 grams. Forget syrup or oil. For that calculations you need the specific weight (density) of the material.
How many percentage 14 kt gold has?
Pure gold is 24 kt. 14 kt gold is (14/24)=.5833 pure. Multiply by 100 and it is 58.33% pure.
How many grams are there in 456 liters of H2SO4?
100% pure H2SO4 doesn't exist
How do you transfer 100 grams into ml?
Only if you have pure water in mind, then: 100 milliliters of pure water weigh 100 grams.
How many molecules of oxgen are needed to react 100 atoms with all the magnesium?
50
Is 100 percent ethanol a pure substance?
Yes, as long as a substance is 100% (purity), it is considered as a pure substance. But logically, there is no such thing as a pure substance.
Distilled pure water has a pH of 7 what is it classified as?
Distilled water is classified as a compound. It has gone through a purification process in order to remove impurities, so all that remains are oxygen and hydrogen molecules hydrogen bonded together forming little H2O molecules :)
