Convert 2.5g mL to the unit g L?
2.5 g per mL = 2,500 g per Litre.
What is the value of x When a 1.63 g sample of MgCl2xH2O is heated to remove all water a mass of 0.762 g remains?
You begin with 1.63 g of MgCl2•xH2O. You end up with 0.762 g MgCl2. That means you lost 1.63 - 0.762 = 0.87 g of H2O. 0.762 g MgCl2 / 95.21 g (molar mass) = .00800 mol MgCl2 0.87 g H2O / 18.02 g (molar mass) = .048 mol H2O x = mol solute / mol solvent x = .048 mol H2O / .00800 mol MgCl2 x = 6 MgCl2•6H2O
How many milligrams of sodium make one gram of salt?
Formula for table salt = NaCl 1.00 g = 1.00 / 58.45 mol = 1.71 x 10-2 mol Mole Na required = 1.71 x 10-2 mol Mass of Na = 1.71 x 10-2 mol x 23.0 g /mol = 0.393 g = 393 mg
What is the molarity of a solution that contains 0.65 moles of NaNO3 in 250 mL of solution?
Molarity (M) = moles of solute (mol) / liter of solution (L)M = mol / LYou have 250 mL of Solution, which is250 mL x ( 1 L / 1000 mL ) = ( 250 / 1000 ) L = .25 LSolute is just what's dissolvedSolvent is just what it's being dissolved inSolution is the solute and the solvent.M = mol / LM = 0.65 mol / 0.25 Liters = 2.6 mol/LThe two numbers that you are given, 0.65 moles and 250 mL both have two significant figures, and the answer is two significant figures (2.6 mol/L)Therefore the answer is 2.6 mol/L.
What is the atomic mass of sulfuric acid?
98.08 g/mol
How do you convert 37 percent HCL in normality?
Density of HCl = 1.186 g/mL Molar Mass HCl = 36.46g/mol We want a concentration in mol/L so we will first convert density into g/L (1.186 g/mL)(1000mL/1L) = 1186 g/L We must now know what density 37% of that is (0.37)(1186 g/L) = 438.82 g/L Now divide this density by the molar mass to cance out the g and give you mol/L (concentration) C = (438.82g/L)/(36.46g/mol) C = 12.04 M Since HCl is monoprotic, 1M = 1N. Therefore, 37% HCl is ~12N
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
How many grams of KBr are required to make 750.0 mL of solution that is 0.0552M molar mass of KBr 119.00gmol?
Multiply the molarity (M, which is in mol/L) with the volume (in L) to get the number of moles needed. Then multiply the result with the molar mass. If you look at the units they will cancel to give an answer in grams. (mol/L)*(L)=mol, (mol)*(g/mol)=g So for the numerical answer you get (0.0552 mol/L)*(0.750 L)*(119.00 g/mol)= 4.93 g KBr
How do you convert gmol to gl?
mol/L
Calculate the molarity of a solution of potassium permanganate and density is 1.04 gmL which contans 15.00 percent by mass?
C [mol/L] = w% * rho [g/mL] *1000 [mL/L] / (100% * M [g/mol] ) = = w% * rho [g/mL] *10 [mL/L%] / ( M [g/mol] ) = = 15.00 % * 1.04 [g/mL] *10 [mL/L%] / ( 158.034 [g/mol] ) = = 0.987 [mol/L] the molarity of the solution of potassium [in mol per liter] equals the content of KMnO4 by mass in percents multiply by density in g/mL multiply by 10 [mL/(L*%)] divide by molar mass of KMnO4 (M = 158.034 g/mol) This gives 0.987 mol/L. Thus the molarity equals approximately 1 M.
A measure of salts in the water is?
Examples are: mol/L, g/L, g/1oo mL.
What is the molarity of a silver nitrate that contains 42.5g AgNO3 in 100mL of solution?
First we need to convert grams(g) to moles(mol) and mL to L, since M(molarity)=mol/L.Ag=107.868N=14O=16 x3=48AgNO3 =169.868 g/mol42.5g x 1 mol/169.868g = .25mol AgNO3100mL x 10-3 L/ 1mL = .1LM=mol/L.25mol/.1L = 2.5M AgNO3
What would be useful for converting g mol to g L?
Molarity
.45g of hydrochloric acid is dissolved in water to make 3.5l of solution what is the pH of HCl?
convert to moles: 0.45 g x 1 mol/36.46 g/mol = 0.0124 mol M = mol/L M = 0.0124/3.5 M = 0.0035 [H+] = 0.0035 pH = -log(0.0035) pH = 2.46
4.00 grams of NaOH have been added to water and made up to 2.00 liters of solution so what is the molarity of this solution?
[4.00 (g) / 40.0 (g/mol)] / 2.00 (L) = [0.100 (mol)] / 2.00 (L) = 0.0500 mol/L
What is dissolving of salt in the water?
This measure is the concentration of NaCl expressed in mol/L, g/L, g/100 g (percentage).
