367.2 g of silver
Explanation:
To find the mass of a substance knowing the number of moles we use the following formula:
number of mole = mass / molecular weight
In the case of silver we use the atomic weight of 108 g/mole.
mass = number of moles × molecular weight
mass of silver = 3.4 moles × 108 g/mole
mass of silver = 367.2 g

It is the same to say, that there are 50g of KBr for every 100g of H₂O
Answer:
pressure of gas are constant describe the relationship between moles and temprature
When a radioactive isotope releases an alpha particle, the atomic number of the atom is decreased by four.
So, the correct answer is B.
