You asked: Which sample represents the greatest number of moles?

Which is the largest number of moles?

Number of moles of Cl2=1g71g=171 mole. Arranging the number of moles of Au, Na, Li and Cl2 in ascending order. Therefore, Lithium (Li) has the highest number of moles i.e. 17.

How do you find the number of moles in a sample?

To find the number of moles in a sample, simply weigh it and divide the weight by the molecular weight. The quotient is equal to the number of moles. Example: How many moles are there in 300 grams of sodium bicarbonate? The molecular weight of sodium bicarbonate is 84 grams/mole.

Which 1 mol sample will have the greatest mass?

Mass – 108 gram. Therefore, 1 mole sample of N2O5 has the greatest mass.

Which mole contains the largest number of atoms?

4 g of hydrogen contains the largest number of atoms.

  • (A) 4 g of hydrogen (molar mass 2) corresponds to 2 moles of molecules or 4N number of atoms where N is the Avogadro’s number (6. …
  • (B) 16 g of oxygen (molar mass 32) corresponds to 0.5 moles of molecules or N number of atoms where N is the Avogadro’s number (6.
THIS MEANING:  Question: What causes nodular acne?

How do you find the greatest number of moles?

Look up the atomic weight (in grams per mole) of each of these 5 elements, and divide the given mass of the element by its atomic weight. That gives the number of moles of each element. The one that gives the greatest number of moles has the greatest number of atoms.

Which sample has the least number of atoms?

The least number of atoms is expressed in the sample of argon gas.

What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

What is the formula for moles?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

What has the greatest mass?

A neutron has a slightly larger mass than the proton. These are often given in terms of the atomic mass unit, where one atomic mass unit is defined as the 1/12th the mass of the carbon-12 atom. Hence, neutrons have the greatest mass.

Which compound has the largest Formula mass?

The answer choice with the largest atomic molar mass is (b) lead. Molar mass is defined as the mass of one mole of an element or compound.

THIS MEANING:  Can any dermatologist prescribe Accutane?

Whats the greatest mass of sulfur?

The maximum mass of sulfur that can be produced from the given volumes of SO2 and H2S is 5.5×104 kg .
