A mole (mol) is a unit of measurement used in chemistry to express the amount of a substance. One mole of a substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. This unit is critical for quantifying chemical reactions and working with amounts of substances at the atomic or molecular scale.

How many gram of water is equal to 2.2 mol of water?
2.2 mol water = 2.2 (mol) * 18 (g/mol) water = 39.6 (mol*g/mol) = 40 g18 g/mol = mol mass of H2O = 2*H + 1*O = (2*1 + 16) g/mol
Determine the empirical formula what compound if a sample contains 0.104 mol K 0.052 mol C and 0.156 mol O?
To find the empirical formula, we need to determine the ratio of each element in the compound. First, find the moles of each element: K = 0.104 mol C = 0.052 mol O = 0.156 mol Next, divide each mole value by the smallest mole value to get the ratio: K = 0.104 mol / 0.052 mol = 2 C = 0.052 mol / 0.052 mol = 1 O = 0.156 mol / 0.052 mol = 3 Therefore, the empirical formula is K2CO3.
What is the mass in atoms of 350 mol of bromine?
To find the mass of 350 mol of bromine, you need to multiply the number of moles by the molar mass of bromine. The molar mass of bromine is approximately 79.9 g/mol. So, 350 mol * 79.9 g/mol = 27965 g. Therefore, the mass of 350 mol of bromine is 27965 grams.

How much octane can react with 0.740 of oxygen?
1 mol of octane (C8H18) reacts with 25 mol of oxygen (O2) to produce 8 mol of CO2 and 9 mol of H2O. Therefore, 0.74 mol of oxygen can react with 0.0744 mol of octane.
How many mol of H are in 4.51 mol H2O?
In 1 molecule of H2O, there are 2 atoms of H. Therefore, in 1 mol of H2O, there are 2 mol of H. So, in 4.51 mol of H2O, there would be 4.51 * 2 = 9.02 mol of H.
How many mmol are in 3.5 mol?
There are 3500 mmol in 3.5 mol. To convert mol to mmol, you multiply by 1000 since there are 1000 mmol in 1 mol.

What is the mole fraction of He in a gaseous solution containing 4.0 g of He 6.5 g of Ar and 10.0 g of Ne?
First, calculate the moles of each gas using their molar masses: He (4.0 g / 4.0 g/mol = 1.0 mol), Ar (6.5 g / 39.9 g/mol = 0.163 mol), Ne (10.0 g / 20.2 g/mol = 0.495 mol). Then, calculate the total moles of gas in the solution: 1.0 mol + 0.163 mol + 0.495 mol = 1.658 mol. Finally, find the mole fraction of He by dividing the moles of He by the total moles of gas: 1.0 mol / 1.658 mol ≈ 0.602.
