4.6to the twelth power plus ten or something like that it has been a while since I have done the scientific notation but where ever you put in the number of zeros. is twelve
After subtracting the volume needed from the volume dispensed, we got a remainder of 35ml
<h3>Subtraction of Numbers</h3>
Given Data
- Volume of Hexane dispensed = 40ml
Let us compute the amount of excess hexane/ the volume that will remain
Remainder = The difference in volume dispensed and the volume needed
Remainder = 40-5
Remainder = 35 ml
The remainder is 35ml

Why does magma composition change during fractional crystallization? Different elements in the magma form crystals at different rates, leaving behind more of the unused elements. ... The crystals are denser than the magma.
Answer:
Pressure = 47.1kPa
Explanation:
V1 = 5.0L
P1 = 94.2kPa = 94.2*10³Pa
V2 = 2V1 = 2 * 5.0 = 10L
P2 = ?
To solve this question, we'll have to use Boyle's law which states that the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant
Mathematically,
V = k/P, k = PV
P1V1 = P2V2 = P3V3=........=PnVn
P1V1 = P2V2
Solve for P2
P2 = (P1 * V1) / V2
P2 = (94.2*10³ * 5.0) / 10
P2 = 47100Pa
P2 = 47.1kPa
The new pressure of the gas is 47.1kPa
