So if the compound has the smallest gram formula mass it has the highest percentage composition by mass of strontium
The mass of an atom is given by the sum of the number of PROTONS and the number of NEUTRONS since ELETRON'S mass is negligible.
The mass is 24+28 = 52.
Animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are mostly round and irregular in shape while plant cells have fixed, rectangular shapes.
Initial volume of the balloon =
= 348 mL
Initial temperature of the balloon
= 
Final volume of the balloon
= 322 mL
Final temperature of the balloon = 
According to Charles law, volume of an ideal gas is directly proportional to the temperature at constant pressure.

On plugging in the values,


Therefore, the temperature of the freezer is 276 K
It would cause a drop <span>but I am not sure double check other answers </span>
