Answer:
6.50M
Explanation:
Molarity, M, is an unit of concentration widely used in analytical chemistry. Is defined as the ratio between the moles of solute (In this case, 5.46 moles) and liters of solution. To solve this question we must find the volume of the solution in liters in to find the molarity of the solution, as follows:
<em>Liters solution:</em>
840mL * (1L / 1000mL) = 0.840L
<em>Molarity:</em>
5.46moles / 0.840L
<h3>6.50M</h3>
Answer: a tornado doesnt have an eye in the middle and its cause by wind and air but a hurricane is way different then a tornado a hurricane is only perduce by air and the force of it can damage more than a tornado and the hurricane also has an eye in the middle and its bigger than a tornado so its C
Explanation:
The answer is 0.8830 mol C3H8.
Here's how the answer was generated:
We do know that all the choices are in moles, in that case, we divide the 38.95 g of propane (C3H8) by the molar mass which is:
C = 12.01
H = 1.01
C3H8 = 3 * 12.01 + 8 * 1.01 = 44.11
Divide 38.95 g by 44.11 g/mol and the answer will be 0.8830 mol C3H8.
Answer:
2
Explanation:
The sample has halved twice.
1/2 of 1/2 is 1/4, and 1/2 of 1 is 1/2.
