How many grams in 4 moles of Na OH?
40*4=160g
How many grams of of NaOH are required to prepare 200 mL of a 0.450 M solution?
Molarity = moles of solute/volume of solution 0.450 M = m/200ml = 90 millimoles, or, what we need; 0.09 moles 0.09 moles NaOH (39.998 grams NaOH/1 mole NaOH) = 3.60 grams of NaOH needed
How many teaspoon are in 40 grams?
There are 8.43 teaspoons in 40 grams.
If you had 40.0 grams of neon light how many mole you have?
Neon's got an atomic number of 20, so if you had 40 grams of neon gas you'd have around two moles of it. But neon LIGHT? Light's weightless, dude.
How many oz are in 40 gram?
40 ounces = 1,133.98 grams.
How many grams in 4 moles of Na OH?
40*4=160g
How many moles of sodium hydroxide are in 40 grams of sodium hydroxide?

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 moles are in 3.75 grams of calcium?
0.09375 moles. Calcium's molar mass is 40, so mass/molar mass (3.75/40) gives 0.09375.
How many grams are in 40 moles of sodium chloride?
The answer is 2337,59 g NaCl.
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
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 grams of sodium hydroxide are there in 0.150 mol?
The molecular weight of sodium hydroxide is 40. Therefore 0.150 moles would be 40 x 0.15 = 6g.
How many atoms are in 131 grams of calcium?
There are 3.275 moles of calcium in 131 grams as relative atomic mass of calcium is 40. Therefore there are 1.972 x 1024 atoms.
20 grams of NaOH to moles?
mass divided by molar mass gives moles: 20 g NaOH / 40 g.mol-1 = 0.5 mol NaOH
How many moles are in 9.8 grams of Calcium?
Strictly, elements such as calcium do not have "moles", but the corresponding term, for Avogadro's Number of atoms of an element, is called "gram atomic mass". For calcium, this number is about 40.08 grams. Therefore, 9.8 grams of calcium is about 9.8/40.08 or 0.24 gram atoms, to the justified number of significant digits.
How many grams of of NaOH are required to prepare 200 mL of a 0.450 M solution?
Molarity = moles of solute/volume of solution 0.450 M = m/200ml = 90 millimoles, or, what we need; 0.09 moles 0.09 moles NaOH (39.998 grams NaOH/1 mole NaOH) = 3.60 grams of NaOH needed
