How many 25grams in 4kg?
To find out how many 25-gram portions are in 4 kilograms, first convert 4 kilograms to grams: 4 kg is 4000 grams. Then, divide 4000 grams by 25 grams: 4000 ÷ 25 = 160. Therefore, there are 160 portions of 25 grams in 4 kilograms.
What percentage of 2 kg is 500 grams?
To find what percentage 500 grams is of 2 kg, first convert 2 kg to grams, which is 2000 grams. Then, divide 500 grams by 2000 grams and multiply by 100 to find the percentage: (500 / 2000) × 100 = 25%. Therefore, 500 grams is 25% of 2 kg.
How many times does 25 g contained in 4 kg?
To find how many times 25 grams is contained in 4 kilograms, first convert 4 kilograms to grams: 4 kg = 4000 grams. Then, divide 4000 grams by 25 grams: 4000 g ÷ 25 g = 160. Therefore, 25 grams is contained in 4 kilograms a total of 160 times.
How many grams in 25 mcg?
There are 0.025 grams in 25 micrograms (mcg). This is calculated by recognizing that 1 microgram is equal to 0.000001 grams. Therefore, to convert 25 mcg to grams, you multiply 25 by 0.000001, resulting in 0.025 grams.
How many milligrams of a drug are in 500 g of a 25 percent Ointment?
25% of 500 grams = 500*25/100 grams = 125 grams.
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.
25 moles of sulfur dioxide how many grams of oxygen does it contain?
25 moles of sulfur dioxide contain 600 grams of oxygen. Each mole of SO2 contains 2 moles of oxygen, and the molar mass of O is 16 g/mol. So, 25 moles x 2 moles = 50 moles of O, which is 50 moles x 16 g/mol = 800 g of O.
What is the percent composition of sulfur in sulfur hexafluoride?
21.95%
How many moles are in 25 grams of UF6?
To calculate the number of moles in 25 grams of UF6, first determine the molar mass of UF6 (uranium hexafluoride) by adding the atomic mass of uranium (238.03 g/mol) to six times the atomic mass of fluorine (19.00 g/mol). This gives a molar mass of 238.03 + (6 * 19.00) = 352.03 g/mol. Next, divide the given mass of 25 grams by the molar mass to find the number of moles: 25 g / 352.03 g/mol ≈ 0.071 moles. Therefore, there are approximately 0.071 moles in 25 grams of UF6.
How many moles are there in 25 grams of Sr?
Sr is 87.6g/mol, and 25/87.6 = 0.285 moles.
How many grams of oxygen will be required to produce 25 moles of sulfur dioxide how many grams of oxygen will be required to produce 25 moles of sulfur dioxide?
800 g oxygen are needed.
How many grams of ammonia are presented in 5.0 l of a 0.050 m solution?
4.25 grams. .050 M = .050 mol/1 L 5.0 L x .050 mol/L (cancel out L to get mol as a unit)= .25 mol Atomic mass of Ammonia (NH3)= 17 g/mol .25 mol x 17 g/mol (cancel out mol to get g as a unit)= 4.25 g
What is the mass of 1.20x10 to the 25th atoms of sulfur?
To find the mass of 1.20x10^25 atoms of sulfur, you need to calculate the molar mass of sulfur and then convert the number of atoms to moles. The molar mass of sulfur is 32.06 g/mol. Once you have the number of moles, you can multiply it by the molar mass to find the mass of 1.20x10^25 atoms of sulfur.
What is the mass in grams of 6.64 mol W?
The molar mass of tungsten (W) is approximately 183.84 g/mol. To find the mass of 6.64 mol of tungsten, you would multiply the number of moles by the molar mass: 6.64 mol W x 183.84 g/mol = 1220.3 g of tungsten.
What is the mass in grams of 0.250 mol of the common antacid calcium carbonate?
The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. To find the mass of 0.250 mol of calcium carbonate, you would multiply the number of moles by the molar mass: 0.250 mol x 100.09 g/mol = 25.02 grams of calcium carbonate.
What is the density of sulfur at twenty five degrees Celsius?
The density of sulfur in grams/cm3 is 2.070. (not at twenty five degrees Celsius)
What is the mass in grams of 1.20x1025 molecules of ammonia NH3?
To find the mass in grams of 1.20x10^25 molecules of ammonia (NH3), you first calculate the molar mass of NH3 (17.031 g/mol). Then, divide the given number of molecules by Avogadro's number (6.022x10^23 molecules/mol) to find the number of moles, and finally, multiply the number of moles by the molar mass to get the mass in grams, which will be approximately 4.08x10^2 grams.
