How do you convert 90 grams of NaCl to moles?
The answer is 1,54 moles.
How do I convert 38 grams of NaCl to moles and formula units?
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams38.0 grams NaCl / (58.5 grams) = .650 moles NaCl
How do you convert 200mL to moles?
1 mole of NaCl is 58.44 g 200 g NaCl * (1 mol NaCl/58.44 g NaCl) = 3.422 mol NaCl There are about 3.4 moles in 200 grams of NaCl.
Explain the following weight approximately 5 grams of NaCl to the nearest milligram?
5 grams of NaCl, or table salt, is equal to 5,000 milligrams. to convert grams to milligrams you simply multiply by 1,000.
The sterile solution used to rinse contact lenses can be made by dissolving 400 mg of NaCl in sterile water and diluting to 100 mL. what is the molarity of this solution?
First, find the moles of NaCl. Because you have 400 milligrams of NaCl convert to grams by dividing 1000mg. 400mg/1000mg = 0.400 grams of NaCl. Now we need to convert to moles. For every mole of NaCl there is 58.44 grams. (22.99g Na + 35.45 g Cl) so using stoichiometry (grams cancel) I get .0068 moles of NaCl. Conver 100 mL to L by dividing by 1000mL. Therefore there is .001 L in the solution. Molarity is moles per Liter. So 0.0068 mols of NaCl / 0.001 L = 6.84 M
How many oz in 325 grams?
325 grams = 11.46 ounces.
How do you convert 325 kg into scientific notation?
convert 325 kg
How many grams of NaCl are in 225 grams of an 18 percent NaCl solution?
The answer is 8 g NaCl.
How many grams of NaCL are produced when 80.0 grams of O2 are produced?
96.75 grams of NaCl
How many grams are there in 325 milligrams?
There are 1000 milligrams in one gram. Therefore, 325 milligrams is equal to 325/1000 = 0.325 grams.
How may grams are in 1.946 moles of NaCl?
1.946 moles NaCl (58.44 grams/1 mole NaCl) = 113.7 grams sodium chloride ======================
How many moles are in 20.0 grams of NaCl?
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams20.0 grams NaCl / (58.5 grams) =.342 moles NaCl
