Likewise, if we know the number of moles of a substance, we can derive the number of atoms or molecules and calculate the substances mass. While atomic mass and molar mass are numerically equivalent, keep in mind that they are vastly different in terms of scale, as represented by the vast difference in the magnitudes of their respective units (amu versus g). This is because marshmallows are made up of mostly sugar, while lead is a metal. 1 ago. This gives us a mass of 1 mole of marshmallows as 3.011 x 10^23 grams.

Which part of a chemical formula indicates the number of copies of molecules or compounds? So, in order to answer the question, "Which sample has the largest mass 1 mole of marshmallows? If the amount of gas in a sample and its temperature are kept constant, then as the pressure of a gas is increased, the volume of the gas decreases proportionately. The first simple relationship, referred to as a gas law, is between the pressure of a gas and its volume. For example, if we know the mass and chemical composition of a substance, we can determine the number of moles and calculate number of atoms or molecules in the sample. We don't have your requested question, but here is a suggested video that might help. Therefore, even though marshmallows have a greater volume, lead is significantly heavier.

Example shows 12 doughnuts as one dozen, 500 sheets of paper as 1 ream, and 6.022 times 10 to the power of 23 molecules as 1 mole. From the moles, calculate the number of atoms and the mass of the elements involved. The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. To do this, we simply need to multiply the mass of one marshmallow by the Avogadro's number. Since the amount of Ar is less than 1 mole, the mass will be less than the mass of 1 mole of Ar, approximately 40 g. The molar amount in question is approximately one-one thousandth (~103) of a mole, and so the corresponding mass should be roughly one-one thousandth of the molar mass (~0.04 g): In this case, logic dictates (and the factor-label method supports) multiplying the provided amount (mol) by the molar mass (g/mol): [latex]9.2\times {10}^{-4}\cancel{\text{mol}}\text{Ar}\left(\frac{39.95\text{g}}{\cancel{\text{mol}}\text{Ar}}\right)=0.037\text{g Ar}[/latex].

How many moles do you have? 5.The two masses have the same numerical value, but the units are different: The molecular mass is the mass of 1 molecule while the molar mass is the mass of [latex]6.022\times {10}^{23}[/latex] molecules. The masses of 1 mole of different elements, however, are different, since the masses of the individual atoms are drastically different. A liter of air contains [latex]9.2\times {10}^{-4}[/latex] mol argon. Due to the use of the same reference substance in defining the atomic mass unit and the mole, the formula mass (amu) and molar mass (g/mol) for any substance are numerically equivalent (for example, one H2O molecule weighs approximately18 amu and 1 mole of H2O molecules weighs approximately 18 g). (A) I mole of marshmallows (C) 1 mole of C02 (carbon dioxide) molecules (B) I mole of Pb (lead) atoms (D) All of these have the same mass.
