How many moles are in 4.75g of sodium hydroxide?
To find the number of moles in 4.75g of sodium hydroxide, you first need to determine the molar mass of sodium hydroxide (NaOH), which is about 40g/mol. Then divide the given mass (4.75g) by the molar mass to obtain the number of moles: 4.75g / 40g/mol = 0.119 moles of NaOH.
What is the mass in grams of 25 mol of sodium hydroxide?
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams/mol. To find the mass of 25 moles of NaOH, you would multiply the number of moles by the molar mass: 25 mol * 40 g/mol = 1000 grams. So, the mass of 25 moles of sodium hydroxide is 1000 grams.
How many grams of sodium hydroxide are there in 0.150 mol?
To find the grams of sodium hydroxide in 0.150 mol, first calculate the molar mass of sodium hydroxide, which is approximately 40 g/mol. Then, multiply the molar mass by the number of moles: 40 g/mol x 0.150 mol = 6 grams of sodium hydroxide.
What is the relative formula mass of ethanol?
The relative formula mass of ethanol (C2H5OH) is 46 g/mol.
What is the density of 3 molar sodium hydroxide in grams per milliliter?
the molar mass of sodium hydroxide is 40g/mol mike
How many elements does sodium hydroxide have?
Sodium hydroxide has the formula NaOH and it contains three atoms, one each of Sodium, Hydrogen and Oxygen.
What is the molar mass of sodium and hydroxide?
The molar mass of sodium (Na) is 22.99 g/mol, and the molar mass of hydroxide (OH) is 17.01 g/mol. To find the molar mass of sodium hydroxide (NaOH), you can add the molar masses of sodium and hydroxide together, which equals 39.00 g/mol.
How many moles are in 4.75g of sodium hydroxide?
To find the number of moles in 4.75g of sodium hydroxide, you first need to determine the molar mass of sodium hydroxide (NaOH), which is about 40g/mol. Then divide the given mass (4.75g) by the molar mass to obtain the number of moles: 4.75g / 40g/mol = 0.119 moles of NaOH.
What is an atomic mass of sodium?
The Relative Atomic Mass of Sodium is 23.
What is the mass in grams of 25 mol of sodium hydroxide?
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams/mol. To find the mass of 25 moles of NaOH, you would multiply the number of moles by the molar mass: 25 mol * 40 g/mol = 1000 grams. So, the mass of 25 moles of sodium hydroxide is 1000 grams.
What is the mass of sodium hydoxide?
Sodium hydroxide (chemical composition NaOH) has an atomic mass of 40 amu which is also 40 grams/mole
What is the relative atomic mass of sodium?
Sodium is a meta element. Atomic mass of it is 23.
What is the relative formula mass of iodine?
The relative formula mass of iodine is 253.8 g/mol.
What would be the total mass of sodium hydroxide?
The total mass of sodium hydroxide would depend on the amount you have. To calculate it, you would need to know the molar mass of sodium hydroxide (which is 40.00 g/mol) and the number of moles you have, which can be determined by weighing the sample and dividing by the molar mass.
An aqueous solution of sodium hydroxide contained in a bottle is labelled 2M. Determine the mass of sodium hydroxide used in preparing?
To determine the mass of sodium hydroxide used in preparing a 2M solution, you need to know the volume of the solution you are preparing. The concentration of 2M means there are 2 moles of sodium hydroxide in 1 liter of solution. You can use the formula: mass = molarity x volume x molar mass to calculate the mass of sodium hydroxide. For example, if you are preparing 1 liter of the solution, the mass would be 2 x 1 x 40 g/mol (molar mass of NaOH) = 80 grams.
How many moles in 20g of sodium hydroxide?
To determine the number of moles in 20g of sodium hydroxide, you need to divide the given mass by the molar mass of sodium hydroxide. The molar mass of NaOH is 40 g/mol (sodium: 23 g/mol, oxygen: 16 g/mol, hydrogen: 1 g/mol). So, 20g NaOH / 40 g/mol = 0.5 moles of sodium hydroxide.
What is the molecular mass of sodium fluoride?
Sodium has a relative atomic mass of 22,989 769 28(2) g/mole. Fluorine has a relative atomic mass of 18,998 403 2 (2) g/mole. Sodium fluoride (NaF) = 22,989 769 28 + 18,998 403 2 = 41,988 172 48 g/mole. NaF is an ionic compound which exists as crystal lattice therefore the term FORMULA MASS is more accurate as compare to MOLECULAR MASS
