How many moles are in gram of NaOH?
moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
Calculate the mass of 2.5 moles of sodium hydroxide?
To calculate the mass of 2.5 moles of sodium hydroxide (NaOH), you need to know the molar mass of NaOH, which is 40 g/mol. Multiply the number of moles by the molar mass: 2.5 moles x 40 g/mol = 100 grams of sodium hydroxide.
How many grams of sodium hydroxide (NaOH) are there in 0.150 mol?
To determine the grams of sodium hydroxide in 0.150 mol, you need to use the molar mass of NaOH, which is 40.00 g/mol (Na = 22.99 g/mol, O = 16.00 g/mol, H = 1.01 g/mol). 0.150 mol NaOH x 40.00 g/mol = 6.00 grams of NaOH.
How many moles of sodium hydroxide are in 40 grams of sodium hydroxide?
To find the number of moles in 40 grams of sodium hydroxide, you first need to calculate the molar mass of NaOH. The molar mass of NaOH is about 40 g/mol. Then, you divide the given mass by the molar mass to get the number of moles. So, 40 grams divided by 40 g/mol is equal to 1 mole of NaOH.
What is the make up of 0.1 sodium hydroxide?
0.1 M sodium hydroxide solution contains 0.1 moles of sodium hydroxide per liter of solution. This corresponds to 0.1 moles of NaOH per 40 g (1 mole) of NaOH, resulting in 4 g of NaOH in 1 liter of 0.1 M NaOH solution.
How many moles are there in 8 g sodium hydroxide?
8 g NaOH x 1 mole NaOH/40 g = 0.2 moles NaOH
How many moles in 30.0 g of NaOH?
To find the number of moles in 30.0 g of NaOH, you need to divide the given mass by the molar mass of NaOH. The molar mass of NaOH is approximately 40 g/mol (sodium: 23 g/mol + oxygen: 16 g/mol + hydrogen: 1 g/mol). Therefore, 30.0 g of NaOH is equal to 30.0 g / 40 g/mol = 0.75 moles.
How many moles of NaOH are in 8 g of NaOH?
To find the number of moles of NaOH in 8 g, first calculate the molar mass of NaOH (sodium hydroxide) which is approximately 40 g/mol (sodium - 23 g/mol, oxygen - 16 g/mol, hydrogen - 1 g/mol). Then, divide the given mass (8 g) by the molar mass to get the number of moles. So, 8 g / 40 g/mol = 0.2 moles of NaOH.
How many moles are in each what 80.0g of NaOH?
To find the number of moles in 80.0g of NaOH, divide the given mass by the molar mass of NaOH. The molar mass of NaOH is approximately 40.0 g/mol (sodium - 22.99 g/mol, oxygen - 16.00 g/mol, hydrogen - 1.01 g/mol). Therefore, there are 2.00 moles of NaOH in 80.0g.
How many moles are in 12.0 g NaOH?
To find the number of moles in 12.0 g of NaOH, you first need to calculate its molar mass. The molar mass of NaOH (sodium hydroxide) is 39.997 g/mol. Next, you divide the given mass by the molar mass: 12.0 g / 39.997 g/mol ≈ 0.30 moles of NaOH.
How many moles of NaOH are present in 20ml of 0.5M NaOH?
To calculate the number of moles of NaOH, we use the formula: moles = molarity x volume (in liters). First, convert 20 mL to liters (0.02 L). Then, use the formula to find: moles = 0.5 mol/L x 0.02 L = 0.01 moles of NaOH present in 20 ml of 0.5M NaOH.
What volume of a 0.540 M NaOH solution contains 15.5 g of NaOH?
Determine the number of moles 15.5 g NaOH 15.5 g NaOH x (1 mole NaOH/39.9971 grams NaOH) = 0.388 moles NaOH Molarity = moles NaOH/L solution 0.540 M = 0.388 moles NaOH/L soln L soln = 0.718 L --> A
How many moles are in gram of NaOH?
moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
How many grams of NaOH are in 350 mL of a 2.5 M of NaOH solution?
To calculate the grams of NaOH in the solution, first determine the moles of NaOH using the molarity and volume. Then, convert moles to grams using the molar mass of NaOH. The molar mass of NaOH is 40 g/mol.
20 grams of NaOH to moles?
To convert grams of NaOH to moles, you need to divide the given mass by the molar mass of NaOH. The molar mass of NaOH is approximately 40 g/mol (sodium: 23 g/mol, oxygen: 16 g/mol, hydrogen: 1 g/mol). Thus, 20 grams of NaOH is equivalent to 0.5 moles (20 g / 40 g/mol).
How many ml of 2.00 M NaOH will it take to have 32.0 g of NaOH?
2.00 M NaOH = 2 moles NaOH/litermolar mass NaOH = 40 g/mole2 moles/liter x 40 g/mole = 80 g/liter(x L)(80 g/L) = 32.0 gx = 0.4 liters = 400 mls needed
What is the mass of 3.42 moles of NaOH?
3.42 moles NaOH (39.998 grams/1 mole NaOH) = 137 grams NaOH
