Is it very white not off white

hydrostone is mostly very white. it can be off white depending on several factors including batch variation, water impurities when mixing, and others. it is usually very white.

What is the density of the powder?

108 lbs/cu. ft dry, 119 lbs/cu ft wet. The 50lb bag of powder is about 24"x16"x7". So that's approximately 1.5cu ft. 50/1.5 gets you about 33 and a 1/3. Right around there. I don't know the exact dimensions of the bag, yo.
