If 4.0*10^25 is atoms of O3 then
4.0*10^25 / 6.20*10^23 = 66.5 moles O3
48 = molar mass O3
48*66.5 = 3192g O3

What is the density of 25 mass and 250 cm?
Density is mass divided by volume. To calculate density we need both mass and volume, so we can't determine the density with just the given information of 25 mass and 250 cm.
What is the atomic mass of 25mg?
The atomic mass of a substance is the mass of one mole of that substance. To calculate the atomic mass of 25 mg of a specific element, you would first need to determine the molar mass of that element. You can then use the molar mass to convert the mass of the sample (25 mg) to the number of moles, and then calculate the atomic mass of that amount.
How do you calculate the specific charge of the nucleus?
The mass of the protons + the mass of the neutron charge of protons mass of proton = 1.67x10-27 mass of neutron = 1.67x10-27 charge of proton = 1.6x10-19 Lead has a nucleon number of 207, and atomic number of 82. Therefore there are 82 protons and (207 - 82) 125 neutrons. mass of ALL protons = 82 x 1.67x10-27 = 1.3694 x 10-25 mass of ALL neutrons = 125 x 1.67x10-27 = 2.0875 x 10-25 charge of ALL protons = 82 x 1.6x10-19 = 1.312 x 10-17 Put into the equation: 1.3694x10-25 + 2.0875x10-25 1.312x10-17 = 2.63 x 10-8 CKg-1
An atom that contains 15 protons and 10 neutrons within its nucleus will have an atomic mass of?
The atomic mass of the atom would be 25 atomic mass units (15 protons + 10 neutrons).
What is the mass of water at 25 degrees Celsius if the volume of water is unknown?
The mass of water at 25 degrees Celsius, without knowing the volume, cannot be determined. Mass is dependent on both volume and density, and without the volume of water given, it is not possible to calculate its mass.
What is the density of 25 mass and 250 cm?
Density is mass divided by volume. To calculate density we need both mass and volume, so we can't determine the density with just the given information of 25 mass and 250 cm.
Can you calculate the mass of a single copper atom?
The mass of a single copper atom is approximately 1.055 x 10^-25 kilograms. This value is determined by the atomic mass of copper (63.55 grams per mole) and Avogadro's number.
What is the atomic mass of 25mg?
The atomic mass of a substance is the mass of one mole of that substance. To calculate the atomic mass of 25 mg of a specific element, you would first need to determine the molar mass of that element. You can then use the molar mass to convert the mass of the sample (25 mg) to the number of moles, and then calculate the atomic mass of that amount.
Does 25 to the power of 10 times 25 to the power of 100 equal 25 to the power of 1000?
No. It is 2510+100 = 25110
What is 8 to the third power plus 10 to the third power divided by 5 to the second power?
(8^3+10^3)/5^2 =(512+1000)/25 =1512/25 =60.480
What is 8.68 time 10 by the power of 25 kg equal?
8.68 times 10 to the power of 25 kg equals 86,800,000,000,000,000,000,000,000kg
How do you calculate the specific charge of the nucleus?

How much is 10 raise to power -15?
10 to the power of -15 is 1/10^15. (1/1,000,000,000,000,000 [15 zeroes])It can also be written as 0.000000000000001 (There are 15 zeroes).OR -1,000,000,000,000,000 (15 zeroes).
What is the number that is one quarter of a googol?
a googol is 10 to the 100th power so a quarter googol is 0.25 x 10 to he hundredth power, or 25 x 10 to the 98th power

How many kilograms are in 25 moles?
To convert from moles to kilograms, you need to use the molar mass of the substance. The molar mass of the substance in question would determine how many kilograms are in 25 moles. You can calculate it by multiplying the number of moles by the molar mass.
