How many moles are present in 1g of ammonia?
To calculate the number of moles in 1g of ammonia (NH3), you first need to determine the molar mass of ammonia. The molar mass of NH3 is approximately 17 g/mol. Then you can use the formula: number of moles = mass / molar mass. So for 1g of NH3, there would be approximately 0.059 moles present.
How many moles are present in 1g of MgO?
2 Mg(OH)2 have 10 atoms.
How many moles are in 12G hydrogen?
To find the number of moles in 12g of hydrogen, we first need to determine the molar mass of hydrogen, which is approximately 1g/mol. Then we can divide the given mass (12g) by the molar mass (1g/mol) to find that there are 12 moles of hydrogen in 12g.
How many moles are present in 4g sodium hydroxide?
To determine the number of moles in 4g of sodium hydroxide (NaOH), divide the mass by the molar mass of NaOH. The molar mass of NaOH is approximately 40g/mol (Na = 23g/mol, O = 16g/mol, H = 1g/mol). Therefore, 4g of NaOH is equal to 0.1 moles.
A 3.0 L solution contains 73.5 g of H2SO4 Calculate the molar concentration of the solution?
First, calculate the molar mass of H2SO4: 2(1.01 g/mol) + 1.01 g/mol + 4(16.00 g/mol) = 98.08 g/mol. Next, convert grams of H2SO4 to moles: 73.5 g / 98.08 g/mol ≈ 0.75 mol. Finally, divide moles of solute by volume of solution to get molar concentration: 0.75 mol / 3.0 L ≈ 0.25 M.

How many moles of hydrogen in 1g?
There are 0.5 moles of hydrogen in 1g, as the molar mass of hydrogen is 2g/mol.
How many moles are present in 1g of MgO?
2 Mg(OH)2 have 10 atoms.
How many moles are in 12G hydrogen?
To find the number of moles in 12g of hydrogen, we first need to determine the molar mass of hydrogen, which is approximately 1g/mol. Then we can divide the given mass (12g) by the molar mass (1g/mol) to find that there are 12 moles of hydrogen in 12g.
How many molecules of water are present in 1g of water?
The answer is 0,166.10e23 molecules.
How many moles are present in 4g sodium hydroxide?

How do you convert grams to molecular mass?
Suppose you have 1g of H2O and you want to convert that to moles. You multiply 1g by the inverse of molar mass to get the moles of H2O: 1g H2O *(1mol H2O/18g H2O)= 0.56 moles of H2O in 1g of H2O. You get 18g = 2(1.008)+1(16.00).
A 3.0 L solution contains 73.5 g of H2SO4 Calculate the molar concentration of the solution?
First, calculate the molar mass of H2SO4: 2(1.01 g/mol) + 1.01 g/mol + 4(16.00 g/mol) = 98.08 g/mol. Next, convert grams of H2SO4 to moles: 73.5 g / 98.08 g/mol ≈ 0.75 mol. Finally, divide moles of solute by volume of solution to get molar concentration: 0.75 mol / 3.0 L ≈ 0.25 M.
How many moles of water are in 250.0ml of water?
Assuming a density of 1g/ml for water, 250.0 mls = 250 g250 g x 1 mol/18 g = 13.9 molesThe answer previously given (247 moles) is incorrect.
How many moles 64 grams of ch4?
First, determine molar mass of CH4: C:12g/mol + 4x H:1g/mol= 16g/mol Then divide by the number of grams. 64g/(16g/mol)= 4 moles of CH4
How many 25cg is equal to 1g?
it is equal because 1g
How many grams in 10mg?
1g = 1000mg 10mg x 1g/1000mg = 0.01g
