I see you have access to the internet. Google 'Kelvin to C', and input 251. You'll get -22.15.
Answer: The answer would be B. Hope this helps.
Explanation:
Answer:
.085 M .
Explanation:
3A(g) +4B(g) ⇋ 5C(g)
4 moles of B reacts with A to form 5 moles of C
.068 moles of B will reacts with A to form 5 x .068 / 4 moles of C
Moles of C formed
= 5 x .068 / 4
= .085 moles .
Answer:
Osmolarity of solution of KCI = 0.40 osmol
Explanation:
Given:
KCL ⇒ K⁺ + Cl⁻
Find:
Osmolarity of solution of KCI
When M = 0.20 M
Computation:
1 mole of KCL = 2 osmol
1 M of KCl = 2 Osmolarity
So,
Osmolarity of solution of KCI = 2 × 0.20
Osmolarity of solution of KCI = 0.40 osmol
