What happens to the density of a material if you have a larger piece of it?(1 point) A. The density will be smaller because the mass remains the same as the volume increases. B. The density will remain the same because mass and volume will both increase in the same way.
C. The density will remain the same because mass and volume will remain the same. D. The density will be greater because the mass increases but the volume remains the same.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

c. 75.7

i think that is the right

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

the answer is barium and copper bromide
