A chemist determined by measurements that 0.015 moles of gold participated in a chemical reaction. Calculate the mass of gold that participated in the chemical reaction. Round your answer to significant digits.

The mass of gold participated in the chemical reaction is 2.95 grams

Explanation:

To calculate the number of moles, we use the equation:

Molar mass of gold = 197 g/mol

Moles of gold participated in the reaction = 0.015 moles

Putting values in above equation, we get:

Hence, the mass of gold participated in the chemical reaction is 2.95 grams

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
