What is the mass of 7.8 x 1018 carbon atoms?
3.011 x 1023 atoms of carbon will weigh about 6 grams One mole of carbon atoms weighs 12.011 grams, and there are 6.022 x 1023 atoms in a moles. So you have half as many atoms, so the mass would be half as much or 6.0055 grams to be precise.
What is the number of atoms in 20.5 g silver?
Silver (Ag) has a molar mass of 107.87g/mol, so by dividing 20.5 by its molar mass, you get how many moles of silver atoms there are in that much silver.(20.5gAg)(1mol/107.87g) = 0.190 moles silver atomsNow, 1 mole = 6.02*1023 (Like a dozen = 12, a mole is just a value.) so if you can't answer in moles, just multiply 0.190 moles by 6.02*10230.190 mol*(6.02*1023/1mol)= 1.14*1023 silver atoms
How much atoms are in 4K3PO4?
1 mole is KNO3 particles. Therefore, 5 moles of KNO3 have 5 x 6.022 x 1023 molecules of KNO3 . Now, 1 molecule of KNO3 has 5 atoms(1 of potassium, 1 of Nitrogen, 3 of oxygen). Therefore, total no. of atoms in 5 moles of KNO3 in KNO3 is 5 x 5 x 6.022 x 1023 =150.55 x 1023 atoms =1.50 x 1025 atoms.
What is the mass of 19 atoms of copper in grams?
Not much! 19 atoms Cu (1 mole Cu/6.022 X 1023)(63.55 grams/1 mole Cu) = 2.0 X 10-21 grams of copper ---------------------------------------
How much would you expect a pile of 1023 sodium atoms to weigh?
1023 Na atoms ( 1mol Na/6.022 X 10^23 )(22.99g Na/1mol Na ) = 3.905 X 10^-20 grams
What is the mass of 7.8 x 1018 carbon atoms?
3.011 x 1023 atoms of carbon will weigh about 6 grams One mole of carbon atoms weighs 12.011 grams, and there are 6.022 x 1023 atoms in a moles. So you have half as many atoms, so the mass would be half as much or 6.0055 grams to be precise.
Which has greater number of atoms a gram of helium or a gram of neon?
Neon is larger because it has more protons, electrons, and neutrons. Look at the element's Atomic Mass for an idea of its size.

What is the mass of a sample of sodium that contains 2980 atoms?
Not much! 2980 atoms sodium [1 mole Na/6.022 X 1023 (atoms)][22.99 grams/1 mole Na] = 1.138 X 10 -19 grams sodium ====================
How much atoms are in 4K3PO4?
1 mole is KNO3 particles. Therefore, 5 moles of KNO3 have 5 x 6.022 x 1023 molecules of KNO3 . Now, 1 molecule of KNO3 has 5 atoms(1 of potassium, 1 of Nitrogen, 3 of oxygen). Therefore, total no. of atoms in 5 moles of KNO3 in KNO3 is 5 x 5 x 6.022 x 1023 =150.55 x 1023 atoms =1.50 x 1025 atoms.
What is the mass of 19 atoms of copper in grams?
Not much! 19 atoms Cu (1 mole Cu/6.022 X 1023)(63.55 grams/1 mole Cu) = 2.0 X 10-21 grams of copper ---------------------------------------
How much would you expect a pile of 1023 sodium atoms to weigh?
1023 Na atoms ( 1mol Na/6.022 X 10^23 )(22.99g Na/1mol Na ) = 3.905 X 10^-20 grams
How much oxygen in grams will be required to react with 0.5 mole of aluminium?
Three atoms of oxygen are required to react with each two atoms of aluminum to form the most common product of reaction between oxygen and aluminum. Therefore, 0.75 mole of oxygen atoms will be required to react with 0.5 mole of aluminum atoms. The atomic weight of oxygen is 15.999; therefore, the mass will be (0.75)(15.999) = 12 grams of oxygen, to the maximum possibly justified number of significant digits.
How much helium is in a balloon that contains 0.54 grams of helium gas?
4 g of Helium will have 6.023 x 1023 atoms and will occupy 22.414 liters. So, 0.54 g of Helium will have 0.37 x 1023 atoms and will occupy 3.03 liters.
How many oxygen atoms and hydrogen atoms does water have?
It depends on how much water you have!
How many atoms are in 4h2o?
Atomic mass- 1.01Formula- grams × (6.02 × 1023) / atomic mass = number of atoms1.00 grams H × (6.02 × 1023) / 1.01 grams = 5.96 × 1023 atoms of hydrogen
What is the difference between formula mass and the molecular mass of a compound?
1 mol is equal to 6.02214179(30)×1023 molecules of the substance. The molecular weight is how much grams these molecules (6.02214179(30)×1023) weigh. Meaning g/mol.
