The total number of atoms in 7.10g of chlorine is 1.204 × 10²³atoms.
HOW TO CALCULATE NUMBER OF ATOMS:
- The number of atoms in a substance can be calculated by multiplying the number of moles in that substance by Avogadro's number as follows:
- no. of atoms = no. of moles × 6.02 × 10²³ mol-¹
- The number of moles in 7.10g of Cl is calculated as follows:
no. of moles = mass ÷ molar mass
no. of moles = 7.10g ÷ 35.5g/mol
no. of moles = 0.2mol
no of atoms = 0.2mol × 6.02 × 10²³
no. of atoms = 1.204 × 10²³atoms.
- Therefore, the total number of atoms in 7.10g of chlorine is 1.204 × 10²³atoms.

Answer: Calories
Explanation: One calorie is the amount of energy required to raise one gram of water one degree Celsius
Assuming it has no electrical charge, your electron count would be equal to the atomic number.
Answer:
Galeras has erupted more than 20 times since the 1500s. Volcanic activity has been frequent in the last five years, including an eruption in January 1993 that killed nine people on a scientific expedition to the volcano summit. Chuck Wood of VolcanoWorld was on Galeras at that time but was not injured
