How many protons does Hafnium 138 with a plus 2 charge have?
The atomic number of hafnium is 72. So there is 72 protons.
How many atoms of oxygen are in 3.33 grams of magnesium hydroxide?
To find the number of oxygen atoms in 3.33 grams of magnesium hydroxide, you first need to calculate the moles of magnesium hydroxide using its molar mass. Then, since the formula of magnesium hydroxide is Mg(OH)2, there are 2 oxygen atoms in each formula unit. Finally, multiply the number of moles by Avogadro's number to get the number of oxygen atoms.
How many valence electrons are in the outer shell of Hafnium with an atomic number of 72?
Hafnium has 2 electrons in its first shell and 8 electrons in its second shell. Therefore, in the outer shell of hafnium, there are 2 + 8 = 10 valence electrons.
How many atoms of carbon are needed to completely react with 2.00 mol of chlorine according to the following equation C plus 2Cl2 CCl4?
C + 2Cl2 ==> CCl4atoms of C needed = 2.00 mol Cl2 x 1 mole C/2 mole Cl2 x 6.02x10^23 atoms/mole = 6.02x10^23 atoms
How many moles of N2 are produced by the decomposition of 1.20 mol of NaN3?
The number of atoms is 45,166.10e23.
How many chlorine atoms are in 0.650 mol of Ca(ClO4)2?
There are 3.12 x 10^23 chlorine atoms in 0.650 mol of Ca(ClO4)2. This is calculated by multiplying the number of moles by Avogadro's number (6.022 x 10^23 atoms/mol) and the number of chlorine atoms in one mole of Ca(ClO4)2 (2).
How many mol of H are in 4.51 mol H2O?
In 1 molecule of H2O, there are 2 atoms of H. Therefore, in 1 mol of H2O, there are 2 mol of H. So, in 4.51 mol of H2O, there would be 4.51 * 2 = 9.02 mol of H.
How many atoms are in 1.54 moles of Bromine?
In 1.54 moles of bromine, there are 9.31 x 10^23 atoms. This is calculated by multiplying Avogadro's number (6.022 x 10^23) by the number of moles of bromine (1.54).
How many moles of nitrogen are required to produce 18 mol of ammonia?
Three moles of nitrogen are required to produce 2 moles of ammonia according to the balanced chemical reaction for ammonia synthesis. Therefore, 27 moles of nitrogen are required to produce 18 moles of ammonia.
How many atoms are in 1.000 mol of H2?
There are 6.022 x 10^23 atoms in 1.000 mol of H2 because Avogadro's number states that there are 6.022 x 10^23 atoms in one mole of any substance. Since H2 consists of two hydrogen atoms, there will be twice this number in 1 mol of H2.
How many atoms are in Ba OH 2?
1 mol Ba X (137.33 g Ba / mol Ba) = 137.33 g Ba2 mol O X (16.00 g O / mol O) = 32.00 g O2 mol H X (1.01 g H / mol H) = 2.02 g HMolar mass of Ba(OH)2 = 171.35 g/mol
How many atoms are in 64 grams of sulfur?
To calculate the number of atoms in 64 grams of sulfur, you first need to determine the molar mass of sulfur (32 g/mol). Then, you divide the given mass by the molar mass to find the number of moles (64 g / 32 g/mol = 2 mol). Finally, you use Avogadro's number (6.022 x 10^23) to find the number of atoms in 2 moles of sulfur, which would be 2 mol x 6.022 x 10^23 atoms/mol.
How many atoms are present in 1.5 mol of sulfuric acid?
One molecule of sulfuric acid, H2SO4, contains 7 atoms (2 hydrogen, 1 sulfur, and 4 oxygen). Therefore, in 1.5 mol of sulfuric acid, there would be 1.5 x 6.022 x 10^23 atoms, which is approximately 9.033 x 10^23 atoms.
How many total atoms are there in 0.550 mol of barium chloride (BaCl2)?
There are 2 atoms of chlorine and 1 atom of barium in each molecule of barium chloride (BaCl2). Therefore, in 0.550 mol of BaCl2, there are 0.550 mol x (1 Ba + 2 Cl) = 0.550 x 3 = 1.65 mol total atoms.
How many oxygen atoms in 2.15 mol of N2O?
There are 9.72 mol of oxygen atoms in 2.15 mol of N2O. This is because each molecule of N2O contains 2 oxygen atoms. So, you can calculate the number of oxygen atoms by multiplying the number of moles of N2O by 2.
How many atoms are in the 1.25x10 mol of mercury within the bulb of a thermometer?
To find the number of atoms in 1.25x10^4 mol of mercury, you need to use Avogadro's number, which is 6.022x10^23 atoms/mol. Multiply the number of moles by Avogadro's number: 1.25x10^4 mol * 6.022x10^23 atoms/mol = 7.5275x10^27 atoms in 1.25x10^4 mol of mercury.
How many atoms are in 1 mole of zinc atoms?
3 moles of Zn is equal to 18.09x1023 atoms. I used Avogadro's Number : 6.03x1023 particles/mol This number is the number of atoms or molecules in a mol of any substance. 3 moles X 6.03x1023 particles/mol = 18.09x1023 atoms
