Question

what is a mole? what is the molar mass of substance? find out the molar mass of SO2?​

Answer 1

Answer:

Mole is a chemical unit used to measure the quantity of atoms or molecules or ions.

Explanation:

SO2 molar mass = 64gram

molar mass is the mass of 1 mole of that substance in gram.

The mole is the unit of measurement for amount of substance in the International System of Units. It is defined as exactly 6.02214076×10²³ particles, which may be atoms, molecules, ions, or electrons.

The molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing the molar masses of its component atoms. We can then use the calculated molar mass to convert between mass and number of moles of the substance.

If you look back at the formula ( SO2 ), you can see that there is one sulfur and two oxygens present. Therefore, the molar mass of sulfur dioxide is [1 × 32.1 + 2 × 16.0] = 64.1 g/mol
