What is the answer to the number of moles present in 1.5 1023 molecules of C2H6?
If you meant 1.5*10^23 and not 1.51023 molecules, see below:1.5*10^23 molecules / (6.022*10^23 molecules/mol)= 1.5/6.022 mol=.25 moles, rounded to two significant figures.
What is the pressure exerted by a vapor confined within a given space?
The pressure exerted by a vapor confined within a given space depends on factors such as temperature, volume of the space, and the number of gas molecules present. It follows the ideal gas law, where pressure is directly proportional to the number of molecules and temperature, and inversely proportional to the volume of the container.
Calculate the number of molecules given grams i.e how many molecules are there in 21.6 grams of CH4?
To calculate the number of molecules in 21.6 grams of CH4, you need to first determine the molar mass of CH4 (methane). The molar mass of CH4 is approximately 16 g/mol. Next, divide the given mass (21.6 g) by the molar mass to get the number of moles. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
How many molecules in aluminum phosphate?
To calculate the number of molecules in aluminum phosphate, we need to know the mass of the sample. Given the mass of aluminum phosphate, we can use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules in the sample.
How many moles are in 3.4 times 10 to the 23 power molecules of H2SO4?
To find the number of moles in 3.4 × 10^23 molecules of H2SO4, you need to divide the given number of molecules by Avogadro's number (6.022 × 10^23 molecules/mol). 3.4 × 10^23 molecules / 6.022 × 10^23 molecules/mol = 0.565 moles of H2SO4.
What is the answer to the number of moles present in 1.5 1023 molecules of C2H6?
If you meant 1.5*10^23 and not 1.51023 molecules, see below:1.5*10^23 molecules / (6.022*10^23 molecules/mol)= 1.5/6.022 mol=.25 moles, rounded to two significant figures.
How many oxygen molecules are there in in 4 g of oxygen?
Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1) This tells us there is 0.125 mol of oxygen gas present. The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23) So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules
What does state of material depend on?
The state of matter depends on the number of atoms / molecules in a given area / volume. If there are more number of molecules, then it will be in solid state and if it is very less molecules then gases. This inturn may depend on the intermolecular force of attraction between the atoms in them. In the case of solids, the force of attraction is high and hence there are more number of molecules present.
A flask contains 0.270 of liquid bromine Determine the number of bromine molecules present in the flask?
To determine the number of bromine molecules present in the flask, you can use Avogadro's number. First, calculate the number of moles of bromine in the flask by dividing the given mass by the molar mass of bromine. Then, multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of bromine molecules.
If 40 percent of a given number is 8?
The given number is 20 (8 divided by 40 then times 100).
What is the pressure exerted by a vapor confined within a given space?
The pressure exerted by a vapor confined within a given space depends on factors such as temperature, volume of the space, and the number of gas molecules present. It follows the ideal gas law, where pressure is directly proportional to the number of molecules and temperature, and inversely proportional to the volume of the container.
What is the number of molecules that cross the membrane in a given length of time?
Flux
36 is what percent of 150?
The formula for finding the percent is =The given number/Total number *100 Here the given number is 36 . The total number is 150 . Therefore Percent = 36/150*100=24%
39 is 40 percent of what number?
When a whole number is given- divide the percent given into the whole number and you will get the original number 39\40 should equal 97.5 great fun you should try it. Works every time.
What is 16 percent of 92?
the X percent of a number is given by x/100 times that number. So. 16 percent of 92 is: 16*92/100
The number of molecules in a given amount of volume is called what?
The number of molecules in a given amount of volume is called the concentration of the solution. It is typically measured in units such as moles per liter (mol/L) or molarity.
When 40 percent of a number is added to the number the result is 182 what is the number?
130.The answer is given by 182/1.4
