Answer : The number of grams of calcium perchlorate is, 0.00253 grams.
Explanation :
Molar mass of calcium perchlorate = 238.9 g/mol
As,
formula units present in 238.9 g of calcium perchlorate
So,
formula units present in
of calcium perchlorate
Therefore, the number of grams of calcium perchlorate is, 0.00253 grams.
Mass<span> is the amount of matter in an object and </span>weight<span> is the measurement of the gravitational pull on an object. The </span>mass <span>of an object is the same no matter where it is, but the </span>weight <span>of an object changes with the location of that object.</span>
The answer is C) Volume . Kilograms is a for of measurement for weight and mass is kinda like weight but mass doesnt change no matter the place or planet.
