Answer:
you have to put a di gram to give you the answers its not letting anyone do it srry
Explanation:
Answer:
1.070MKCl
Explanation:
So we know that the original formula is M= n/L (n being moles of solute, L being liters of solvent)
Since we do not have liters in this problem, we would need to convert milliliters to liters
<u>213 mL= 0.213 L</u>
We then see that we do not have moles, but we do have a mass, being <u>17.0 g.</u> we would need to convert these grams to moles, giving us <u>0.228 mol.</u>
Then, you would plug in <u>0.228 for your n</u>, and now you are ready to solve your original formula, plugging everything in.
M=n/L
M=0.228 mol/0.213L
M= 1.070MKCl
I know this was long, but I hope this helps (:
D=m/v d=63.5g/11.6cm3=5.47g/cm3
A greenhouse gas is one that leads to global warming, by the absorption of infra-red radiation re-emitted by the ground. Common greenhouse gases include carbon dioxide and methane. Surprisingly, water vapour (which contains only oxygen and hydrogen) is also a greenhouse gas and can contribute to global warming.
Answer:
V₂ = 1592.32 L
Explanation:
Given data:
Initial number of moles = 1.54 mol
Initial volume = 383.2 L
Final volume = ?
Final number of moles = 6.4 mol
Solution:
Formula:
V₁/n₁ = V₂/n₂
V₁ = Initial volume
n₁ = initial number of moles
V₂ = Final volume
n₂ = Final number of moles
now we will put the values in formula.
V₁/n₁ = V₂/n₂
383.2 L / 1.54 mol = V₂/ 6.4 mol
V₂ = 248.8 L/mol ×6.4 mol
V₂ = 1592.32 L
