Answer:
23 kPA
Explanation:
95kPa = 24kPA (CO2) + 48 kPa (N) + x kPa (O)
24kPA(CO2)+ 48kPA (N) = 72 kPA
95kPA - 72kPA= 23kPA (O)
<h3>
<u>Answer</u> - 5.85g</h3>
<h3>
<u>Solution</u> - </h3>
Using the concentration equation, m = CVMo where m is the mass of solute, C is the concentration (M), V is the volume of solution (L) and Mo is molar mass of the solute (g):
Given,
Molar mass of NaCl, M = 58.5g/mol
Volume of the solution, V= 100ml = 0.1L
Molarity, S= 1M
Mass of the solute,W=?
W=SMV
= 1×58.5×0.1
= 5.85g
Answer: the answer is C oxidizing
