How many molecules are in 4.21 grams of water?
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
How many moles of ammonium sulfate are in 150g sample?
150/132 equals 1.136moles
How many moles of sulfuric acid are present in 0.550 L of a 0.150 M sulfuric acid solution?
.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
How many moles are there in 150 grams of Al(OH)3?
The approximate molar mass of Al(OH)3 = 27 + 48 + 3 = 78 g/mol150 g x 1 mol/78 g = 1.92 moles
How many moles of atoms are in 150 g sulfur?
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.
If 20.0 mL of 150 M NaOH are used in a titration how many moles of NaOH are used?
150 M NaOH = 150 mole / liter 20.0 mL = 0.0200 L 150 * 0.0200 = 3 moles
How many moles of (NH4)2S are there in 150 g of (NH4)2S?
150 g x 1 mol/68.154 g = 2.2 moles (2 sig figs)
How many molecules are in 4.21 grams of water?
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

How deep can moles dig?
150

5.0 times 10 to the 24th power molecules is how many liters?
150
150 ml gas how many grms?
This depends on many things including temperature, pressure, number of moles and molecular weight or the density
How many moles of atoms are in 150 g sulfur?
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.
How many moles are in 150 grams what compound NaCl?
Divide by molar mass of NaCl (not NaCI ! ) which is 58.44 g/mol NaCl.
You were hired by a laboratory to recycle 6 moles of silver ions You were given 150 g of copper How many grams of silver can you recover Is this enough copper to recycle 6 moles of silver ions?
No you need more copper
