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.
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.
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
The atomic mass of the atom would be 25 atomic mass units (15 protons + 10 neutrons).
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.
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.
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.
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.
No. It is 2510+100 = 25110
(8^3+10^3)/5^2 =(512+1000)/25 =1512/25 =60.480
8.68 times 10 to the power of 25 kg equals 86,800,000,000,000,000,000,000,000kg
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
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
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).
intNumOfQuarters = intNumOfPennies \ 25 'calculate number of qaurters' intNumOfDimes = (intNumOfPennies Mod 25) \ 10 'calculate number of dimes' intNumOfNickels = ((intNumOfPennies Mod 25) Mod 10) \ 5 'calculate number of nickels' intNumOfPenniesleft = (((intNumOf
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.
