Which of the following has more atoms: 1.10 g of hydrogen atoms or $14.7 \mathrm{g}$ of chromium atoms?. Okay, So which has more Adam’s 10 grams of calcium or 10 grams of carbon? It should be whichever Adamis smaller and in this case, carbon is smaller
s.If the speed can be measured within accuracy of 2% , calculate the uncertainty in the position. [2]
The uncertainty in the speed is 2%,i.e.,Δv=45×2100=0.9ms−1. This is nearly ∼1018 times smaller than the diameter of a typical atomic nucleus
Final Answer: uncertainty in position is 1.46×10−33m
Molar mass [3]
Atomic mass is based on a relative scale and the mass of 12C (carbon twelve) is defined as 12 amu.. Why do we specify 12C? We do not simply state the the mass of a C atom is 12 amu because elements exist as a variety of isotopes.
Each carbon atom has the same number of protons and electrons, 6. 12C has 6 neutrons, 13C has 7 neutrons, and 14C has 8 neutrons and so on
All the masses of the elements are determined relative to 12C.. By the way, the mass of an element is not equal to the sum of the masses of the subatomic particles of which the element is made!

3.2 Determining Empirical and Molecular Formulas – Chemistry 2e [9]
The previous section discussed the relationship between the bulk mass of a substance and the number of atoms or molecules it contains (moles). Given the chemical formula of the substance, one may determine the amount of the substance (moles) from its mass, and vice versa
The elemental makeup of a compound defines its chemical identity, and chemical formulas are the most succinct way of representing this elemental makeup. When a compound’s formula is unknown, measuring the mass of each of its constituent elements is often the first step in the process of determining the formula experimentally
For example, consider a gaseous compound composed solely of carbon and hydrogen. The percent composition of this compound could be represented as follows:
Molar Mass – Introductory Chemistry [10]
The mole is represented by Avogadro’s number, which is 6.022×1023 atoms or molecules per mol.. – The mole allows scientists to calculate the number of elementary entities (usually atoms or molecules ) in a certain mass of a given substance.
– The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.
The chemical changes observed in any reaction involve the rearrangement of billions of atoms. It is impractical to try to count or visualize all these atoms, but scientists need some way to refer to the entire quantity
