## Which sample contains the greatest number of moles of CI?

(d) 2.2 mol Mg(ClO4)2 contains the greatest number of moles of Cl.

## How do you know which sample contains the greatest number of molecules?

When the mass of a compound is given, we can find the number of moles of that compound by using its molar mass. We know that 1 mole of the compound contains 6.022×1023 6.022 × 10 23 molecules, so we can find the molecules of the given compound when the moles of the compound are known.

## Which element has the largest mole?

Uranium (atomic number 92; molar mass = 238.03 g/mol) has the largest molar mass of any element naturally found on Earth.

## 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.

## How many molecules are there in 88 gram of CO2?

of oxygen atoms in 88 g of CO2 contains is 2×2×6.022×1023 atoms. Hence, the no. of oxygen atoms present in 88 g of CO2 is 2.41×1024 atoms. Now, we know that one molecule of CO contains one atom of oxygen.

THIS MEANING:  Can water clear acne scars?

## Which has the lowest number of molecules?

D. 0.1 mole of \$C{{O}_{2}}\$ gas. Hint: Find out the number of moles of carbon dioxide gas in each case, the option having the least number of moles will have the least number of molecules too. It means that the number of moles is directly proportional to the number of particles.

## Which has the largest number of molecules?

As we can see that, water has the highest value for the number of moles in respect to other compounds. So, the largest number of molecules are present in water.

## What do you call the element from atomic number 57 71?

The elements from atomic number 57 to 71 are called Lanthanides. They are called lanthanides, since lanthanum is chemically identical to the elements in the sequence. … The lanthanides are between Barium and Hafnium.
