Mole to atom conversions require Avogadro's constant, 6.02 × 1023. Take the number of moles and multiply it by Avogadro's constant to get number of atoms. It is usually expressed in scientific notation.
1.50 mole F × (6.02 × 1023) = 9.03 × 1023 atoms F
6.023 x 1023 atoms = 1 mole
So, 1.5 x 1023 atoms = 0.25 mole
1 mole = 6.022 x 1023 and Glucose is C6H12O6 so there are 24 atoms in 1 molecule. So there are 6.022 x 1023 x 1.5 x 24 = 2.17 x 1025 total atoms.
This number is approx. 9,033.10e+23 atoms.
The answer is 9,033 211 935 molecules.
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
150/132 equals 1.136moles
.150 M is the molarity of the solution, which is the number of moles per liter. So all you need to do is multiply the molarity by the number of liters. So .150 moles/liter x .550 L = .0825 moles
The approximate molar mass of Al(OH)3 = 27 + 48 + 3 = 78 g/mol150 g x 1 mol/78 g = 1.92 moles
The reaction equation is 2 NaHCO3 + H2SO4 = 2 CO2 + 2H2O + Na2SO4. This means that for every mole of sulfuric acid, two moles of NaHCO3 are needed. 150 grams of H2SO4 is 1.53 moles, so 3.06 moles of NaHCO3 are required.
150 M NaOH = 150 mole / liter 20.0 mL = 0.0200 L 150 * 0.0200 = 3 moles
150 g x 1 mol/68.154 g = 2.2 moles (2 sig figs)

This depends on many things including temperature, pressure, number of moles and molecular weight or the density
30 / (1/5) = 30 * (5/1) = 150
The reaction equation is 2 NaHCO3 + H2SO4 = 2 CO2 + 2H2O + Na2SO4. This means that for every mole of sulfuric acid, two moles of NaHCO3 are needed. 150 grams of H2SO4 is 1.53 moles, so 3.06 moles of NaHCO3 are required.
Divide by molar mass of NaCl (not NaCI ! ) which is 58.44 g/mol NaCl.
