Answer:
14.06 M
Explanation:
Molarity: moles of a solution / liters of a solution
We convert 569ml into liters for the equation by dividing milliliters by 1000.
569/1000 = 0.569L
Now that we have Liters we can do moles of a solution / liters of a solution:
8 / 0.569 = 14.06 M
Advantages
less wasted energy
Reduces fossilisation
Disadvantages
- Expensive
- doesn't look nice ( apparently)
Answer:
(a) C5H8O2
(b) C2H2Cl2
(c) CH2
(d) CH
Explanation:
We need to find the proportion of the atoms in whole numbers. Given the percentages we can calculate the number of moles and find their proportions.
Assume 100 g and given the atomic weights the moles are calculated.
(a) C = 59.9/ 12.01 = 4.98 ≈ 5.00
H = 8.06/1.007 = 8.00
O = 32/15.999 = 2.00
C5H8O2
(b) C= 24.8/12.01 = 2.06≈ 2.00
H = 2.0/1.007 = 1.99 ≈ 2.00
Cl = 73.1/ 35.453 = 2.06 ≈ 2.00
C2H2Cl2
(c) C = 86/12.01 = 7.16
H= 14/1.007 = 13.90
7.16:13.90 ≈ 1:2
CH2
(d) C = 92.30/12.01 = 7.68
H = 7.7 / 1.007 = 7.65
7.68:7.65 ≈ 1:1
CH
Pretty sure it’s b! mark as brainliest
Explanation:
<h2>1.-Ate-contains 3 elements in which one is oxygen</h2><h2>2.-ite-contains 3 elements in which one is Oxygen but the oxygen is less than that of -Ate</h2><h2>3.-ide has 2 elements</h2>
