Weights of atoms and isotopes are from NIST article.

Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol.

(1 u is equal to 1/12 the mass of one atom of carbon-12)

Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u).

To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.Įxamples of molecular weight computations:ĭefinitions of molecular mass, molecular weight, molar mass and molar weight Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.Ĭomputing molecular weight (molecular mass)

Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg.

Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. Lying beside the test tubes are three labels: potassium iodide, KI, silver nitrate, AgNO3, and sodium sulfide, Na2S.Computing molar mass (molar weight)To calculate molar mass of a chemical compound enter its formula and click 'Compute'. Three colorless solutions in test tubes, with no labels, are in a test tube rack on the lab bench. 7.09% 3 is 1/3 is equivalent to 33 1/3% what percent is equivalent to 2/3? A 33 2/3% Round to the nearest tenth of a percent if necessary. What is the concentration of M2 ions at equilibrium?ġ. A 0.150-mole quantity of M(NO3)2 is added to a liter of 0.840 M NaCN solution. The formation constant of ^-2 is 7.70 × 10^16, where M is a generic metal. (1 qt = 2 pt) 0.140 pint= 66.2 mL 150.01g mass container and syrup 104.70g mass empty container When 0.140 pint of syrup is added, the total mass of the container and syrup is 150.01 g. Show calculations for how you will prepare 250 mL of 0.1 M AgNO3 solution from solid AgNO3 and water Give the reagent amounts and units.Ī syrup is added to an empty container with a mass of 104.70 g. How many grams of Ag2CO3 will precipitate when excess K2CO3 solution is added to 70.0 mL of 0.692 M AgNO3 solution? 2AgNO3(aq) + K2CO3(aq) -> Ag2CO3(s) + 2KNO3(aq) Write an expression for the balloon's height at 'm' minutes. Make a table to show the pattern of heights. Find it's height after six, eight, and ten minutes. A hot air balloon is at a height of 2,250 feet.

How many grams of NaCl would be required to react with 132 mL of 0.719 M AgNO3 solution? Answer in units of grams.ģ.

Silver nitrate (AgNO3) reacts with sodium chloride as indicated by the equation AgNO3 + NaCl → AgCl + NaNO3.

can you please explain the universal steps for me What mass of solid AgBr is produced when 100.0 mL of 0.150 M AgNO3 is added to 20.0mL of 1.00 MNaBr? i keep getting the answer 3.75 g however when i checked in the back of the book it gives me 2.82 g. Mix 1 mL of the 100 mM sucrose and 199 mL of water. Mix 50 mL of the 100 mM sucrose and 150 mL of water. Mix 20 mL of the 100 mM sucrose and 180 mL of water. How will you make a 200 mL solution of 1 mM sucrose from a 0.1 M sucrose solution? 1.
