Cl2(g) is the natural form that chlorine exists in. If they ask the mass of 1 molecule of chlorine gas, it would be 71g. But since you are calculating empirical formula, you want the mass of chlorine ATOM, not molecule. So, the answer is 35.5g. M) and the mass of the lighter isotope (i.e. For Cl use 35 not 35.5, or, for Br use 79 and not 80) 35 Cl: 37 Cl exists naturally in an almost 3:1 ratio, so we observe peaks at 'M' (molecules with an atom of 35 Cl) and 'M+2' (molecules an atom of 37 Cl) are obtained with relative intensity 3:1.

Computing molar mass (molar weight)

To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use:
  • Any chemical element. 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.
  • Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg
  • parantesis () or brackets [].
  • Common compound names.
Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose.
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.

Computing molecular weight (molecular mass)

To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.
Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2.

Definitions of molecular mass, molecular weight, molar mass and molar weight

  • Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
  • Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
Weights of atoms and isotopes are from NIST article.

Atomic Weight Of Cl

Learning Objectives

  • Define mass ratio.
  • Calculate the mass ratio of an element in two different compounds.

What are the similarities and differences between these two equations?

One of the fundamental laws of chemistry deals with the fact that we cannot (using chemical means) create or destroy matter. When a reaction is run, the number of atoms of each specific type must be the same on both sides of the equation. For some materials, it turns out that one element can combine with a second element in more than one ratio. Carrying out mass ratio calculations helped establish the law of multiple proportions.

Mass Ratio Calculations

Copper reacts with chlorine to form two compounds. Compound A consists of 4.08 g of copper for every 2.28 g of chlorine. Compound B consists of 7.53 g of copper for every 8.40 g of chlorine. What is the lowest whole number mass ratio of copper that combines with a given mass of chlorine?

Ricoh printers driver download for windows. Step 1: List the known quantities and plan the problem.

Known:

  • Compound A = 4.08 g Cu and 2.28 g Cl
  • Compound B = 7.53 g Cu and 8.40 g Cl
Mass

Apply the law of multiple proportions to the two compounds. For each compound, find the grams of copper that combine with 1.00 g of chlorine by dividing the mass of copper by the mass of chlorine. Then find the ratio of the masses of copper in the two compounds by dividing the larger value by the smaller value.

Compound A: [latex]displaystylefrac{4.08text{ g Cu}}{2.28text{ g Cl}}=frac{1.79text{ g Cu}}{1.00text{ g Cl}}[/latex]

Compound B: [latex]displaystylefrac{7.53text{ g Cu}}{8.40text{ g Cl}}=frac{0.896text{ g Cu}}{1.00text{ g Cl}}[/latex]

Mass Of Cl 35

Compare the masses of copper per gram of chlorine in the two samples.

[latex]displaystylefrac{1.79text{ g Cu (in compound A)}}{0.896text{ g Cu (in compound B)}}=frac{2.00}{1}=2:1[/latex]

The mass ratio of copper per gram of chlorine in the two compounds is 2:1.

Step 3: Think about your result.

Mass Of Cl

The ratio is a small whole-number ratio. For a given mass of chlorine, compound A contains twice the mass of copper as does compound B.

Summary

  • The mass ratio gives the mass of an element that is found in combination with another element.
