Answer: 97

Explanation:

The element Ru is Ruthenium which has 44 protons.

In this case, our atom is an isotope with 53 neutrons.

With this information, we can use the mass number formula to find this atom's mass number.

mass number = protons + neutrons

mass number = 44 protons + 53 neutrons

mass number = 97

pishuonlain [190]

Answer: A fewer number of particles of the sample will dissolve in 1 minute.

That is because normally the solubility and rate of solubility of the salts in water increase with the temperature. This is, the higher the temperature the higher and faster the number of particles that the water can dissolve. So, at 70°C more particles will be dissolved in water in 1 minute than at 20°C.
