Answer:
A. -10,000
Explanation:
When x approaches zero, the graph tells us that F(x) either becomes extremely large or extremely small. The best answer is therefore A: -10,000. Best, because we aren't given the exact value of x, but clearly the other results require that x be greater than 1 or less than -1, which is far from zero.
CaSO4 has a molar mass of 136.145 (40.08+32.065+16*4).
17 g / 136.145g= ~0.125 formula units (0.12 with appropriate significant figures)

Hello there!
In this case, according to the given STP (standard pressure and temperature), it is possible for us to realize that the equation to use here is the Avogadro's law as a directly proportional relationship between moles and volume:
In such a way, given the initial volume and both initial and final moles, we can easily compute the final volume as shown below:
