Answer:
0.015 moles
Explanation:
- One mole of a compound contains molecules equivalent to the Avogadro's constant, 6.022 × 10^23.
- That is, 1 mole of a compound will have 6.022 × 10^23 molecules.
In our case, We are given 8.96 x 10^21 molecules of KBr
We need to find the number of moles in 8.96 x 10^21 molecules
1 mole of KBr = 6.022 × 10^23 molecules.
8.96 x 10^21 molecules = ?
Therefore;
(1 × 8.96 x 10^21 molecules ) ÷ 6.022 × 10^23 molecules.
= 1.488 × 10^-2 moles
= 0.01488 moles
= 0.015 moles

Explanation:
I don't know how to show the work for it without pencil and paper but go from there, Good Luck!
Answer:
1.05
Explanation:
P1 over t1 is equal to P2 over T2, then solve for X
X/199= 1.2/227
I have my biology notebook if that helps
Answer:
