How many grams of argon are in 100 mole?
To find the mass of argon in grams for 100 moles, you can use the molar mass of argon, which is approximately 40 grams per mole. Therefore, the mass of 100 moles of argon would be calculated as follows: 100 moles × 40 g/mole = 4000 grams. Thus, there are 4000 grams of argon in 100 moles.
How many grams in 4 moles of Na OH?

How many moles in 200 grams of calcium?
There are 5 moles of calcium in 200 grams of calcium. This calculation is based on the molar mass of calcium, which is approximately 40 grams per mole.
If you have 60 grams of sodium hydroxide NaOH (FW 40 gramsmole) how many moles of sodium hydroxide would you have?
60 g NaOH x 1 mole NaOH/40 g NaOH = 1.5 moles 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.
How do you convert 40 mmol of Sodium to grams?
A mole is 6.022*10^23 of a substance. An element's atomic mass, the number below the element's atomic symbol on the periodic table, is the number of grams one mole of that substance weighs. Multiply the number of moles of substance (here, 40 if you meant 40 moles or .04 if you meant millimoles) by the atomic mass of the substance (here, sodium's is 22.98977) to get the final answer in grams.
How many grams are in 40 moles of sodium chloride?
The answer is 2337,59 g NaCl.
How many moles are in 3.75 grams of calcium?
To find the number of moles in 3.75 grams of calcium, divide the mass of calcium by its molar mass. The molar mass of calcium is approximately 40.08 g/mol. Therefore, 3.75 grams of calcium is equal to 0.0936 moles.
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 needed to prepare 250mL of 205 M of NaOH?
To calculate the grams of NaOH needed, you first need to find the moles of NaOH required: 205 M concentration means 205 moles/L. So, for 250 mL (0.25 L), you multiply 0.25 L by 205 moles/L to get 51.25 moles. Finally, using the molar mass of NaOH (40 g/mol), you can convert moles to grams by multiplying 51.25 moles by 40 g/mol to find you need 2050 grams 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 moles are there in 23 grams of sodium?
First of all, we should know what a mole and molar mass of an element means. Then answering this question would be easy. Mole is a number( like pi, 1, 2, etc.). It is approximately 6.0225 *1023 . 1 mole of anything is same as the number of atoms in 12 grams of Carbon C12 sample. The mass of mole of an element/compound is called it's molar mass expressed in grams. The molar mass of a monoatomic element is equal to it's mass number. So, we know Ca's mass number = 40. that means 1 mole of Ca weighs 40 grams. =>1/40 mole of Ca weighs 1 gram. =>(1/40)*23 moles of Ca weighs 23.0 gram. =>0.575 moles of Ca weighs 23.0 gram. So there are 0.575 moles of Ca atoms in 23.0g of Ca
