How many moles of oxygen are there in a thirty six centimeter cube of the gas at room temperature and pressure?
What you need to know to work this out is that:- Moles of gases at standard temperature pressure (With P and T constant) are proportional to the volume they occupy, divided by their specific gas constant.
Please show work How many moles would there be in 300 ml of of a 1.5 M solution?
To find the number of moles, use the formula: moles = Molarity (M) x Volume (L). First, convert 300 ml to liters by dividing by 1000: 300 ml / 1000 = 0.3 L. Then, calculate moles = 1.5 M x 0.3 L = 0.45 moles. Therefore, there would be 0.45 moles in 300 ml of a 1.5 M solution.

How many molecules are there in 60.0g of acetic acid C2H402?
Find the moles using the formula: moles= grams/molecular mass In this case, molecular mass = 24+4+32 = 60g/mol so 66/60 = 1.1 moles Then, using avogadro's constant, work out the number of molecules. n(molecules) = number of moles x 6.02x10^23 =1.1x 6.02x 10^23 =?
How many grams of O2 are in 15 moles of O2. with work shown?
15 moles O2 (32 grams/1 mole O2) = 480 grams
Why do chemists use moles in their calculations and measurements?
Chemists use moles in their calculations and measurements because it allows them to work with a consistent unit of measurement for atoms and molecules, making it easier to compare and analyze different substances.
How do you work out the number of moles of unknown compound if you are only given the molar mass?
To find the number of moles from molar mass, divide the mass of the compound by its molar mass. The formula is: Moles = Mass (g) / Molar Mass (g/mol). This will give you the number of moles of the unknown compound.
Why do we want to use the concept of moles in chemistry?
The concept of moles in chemistry is used to easily measure and compare the amounts of different substances. It allows us to work with large numbers of atoms or molecules in a more manageable way, making calculations and experiments more efficient and accurate.
